Analysis

I learned a little bit, but I haven't mastered it at all.It should be cold at one end and hot at the other, but I didn't expect that one end is hot and the other end is even hotter.Is there expert tell me where I am wrong?

I’m have a CFD project with an oil/water heat exchanger in a hydraulic tank. I would be studying how effective the cooler is at lowering the temperature of the oil over a given time so, it would be a transient analysis. The cooler has two cores with water looping through them in series. Each core has 182 copper tubes that are 0.4 mm thick and 170 aluminum fins that are 0.25 mm thick with a spacing of about 1.73 mm. I want to do cunjugate heat transfer across the solid geometry, but with so many components that are thin walled, the number of cells in the mesh woul be astronomical.  I'm looking for suggestions on a basic approach to this analysis.  Can the tubes and fins be compressed to mid-surfaces and run in CFA? That would require fewer cells in the solid domains. I see that there is something buried in the mesher about two fluid heat exchangers, but I haven't been able to find information on how to utilize that. Some direction there would be helpful too.  &n

Hello everyone, I am currently working on a Creo Flow Analysis for a vacuum system. I was able to successfully set up an internal flow simulation, but I am facing errors when trying to include the ambient airflow around the nozzle.What I have set up successfully:Internal flow only:Inlet (nozzle entry): Set as 101325 Pa (atmospheric pressure).Outlet (nozzle exit, connected to the vacuum system): Defined as Volumetric Flux 400 m³/h (0.111 m³/s).This setup runs without issues.What I am trying to add:I want to simulate how air is being drawn from the surroundings into the nozzle.To do this, I added a large surrounding box to represent the air environment.The walls of the box are defined as inlet and outlet pressures (atmospheric pressure, 101325 Pa).The issue:When I include the ambient air domain, I get errors on the inlet and outlet boundaries of the nozzle.It seems like Creo does not handle both the internal flow and external airflow together properly.My goal is to see where the noz

can you tell me how to use this function. where is the Creat linked volume？

Hello, I am trying to render a simple fluid flow simulation in Simulation Live for Creo 9.0.1.0. When I add particles to the display it runs at about 2 FPS, this is with the Performance options set all the way to the left for "Speed". At this time, Creo is using 0-2% of my GPU.However, what is interesting, is when I rotate the model, the GPU usage jumps up to 60-70% and the FPS is smooth (closer to 30 FPS or more).  I want to be able to have this speed and quality of animation without having to continuously rotate the model. Is this possible?   

So, I joined a company that uses CREO 10. When I got here, I found out they also have SW Pro with SIM Pro with ECAD thermal analysis. I asked why and they stated that CREO Sim doesn't provide ECAD thermal analysis. So, I personally would rather use SW for our CAD - especially since we do the ECAD sim in SW already. Otherwise, it would be great to find a solution for CREO and move away from SW Sim. Now I know Ansys runs within CREO - but does CREO have a basic ECAD thermal simulation that is acceptable? Keep in mind money is the driving factor here - so spending 10's of thousands of dollars is not an option. So, the process of going from CREO to SW is just painful. If CREO has a decent solution it would solve a ton of issues. Is CREO simulation - especially for ECAD that bad? So, what does SW ECAD Sim offer - it allows for PCB board simplification allowing to input the PCB layers with copper weights - it allows for 2-R definition of electrical components - it allows for CFD an

I have been performing mechanism analysis for some time but I usually use align two entities and mate two entities  option when creating initial point snapshots, either method gives me same results. I wonder what's the main difference between two options , I would like a very good use case to differentiate between them both. 

Hello,I'm currently trying out the new Ansys Simulation Module. By doing so I wanted to run a couple of simulations but the Buttons "run" and "Generate Mesh" are greyed out. I've checked with a couple of different models and I've also created one just for checking the behavior. Even with just a cube, I can reproduce this behavior (Screenshots attached). Has anyone come across this problem and knows how to solve it? I'm starting to think it must have something to do with some settings?    Any help is appreciated! 

I am using Creo Simulate Release N/A and DatecodeN/AI am running a simulation on a two piece aerofoil. The applied pressures are entered via .fnf files generated using Creo Flow Analysis. The aim is to run a baseline configuration and obtain the Fx and Fz loads to give lift and drag. The next step is to vary the angle of the aerofoil flap and compare the values for Fx and Fz to baseline.Unfortunately the assembly will run in baseline configuration and with the flap angle increased by 1 degree, but fails if the flap angle is reduced by 1 degree. This happens at other angles too but I cannot see why.Here are the errors that I facedSingular mapping, solid element: 1345420The design study terminated abnormally.The element with DBID 1345420 has invalid geometry.

I am trying to perform a Vibration Analysis on an assembly in Creo Simulate (in Creo Parametric Version 10). The only input data I have is the Vibration Amplitude vs. Frequency table below. I was wondering if it is possible to do an analysis in Simulate with this type of data. Is so, would it fall under the "Shock" category under the  "New Dynamic" analysis option? Or would it be under another category? An input on this matter would be helpful. Thanks.   

Hi all,I'm trying to automate the process of taking screenshots of simulation models from different angles in Creo Simulate. My goal is to change the view orientation without triggering a full recalculation of the model.I discovered that Creo Simulate can write the view matrix directly into an .rwt file. So, I wrote a simple Python script that generates a custom view matrix and inserts it into a template .rwt file. When I reload the file, the view updates to the new orientation as expected.However, there's a problem: instead of simply rotating the model, Creo seems to fully regenerate or recalculate the view, which adds unnecessary delay. I was hoping for a lightweight change—just to adjust the camera/view angle without triggering a full redraw or computation.My question is:Is there a way to apply a custom view matrix directly to the current view in Creo Simulate, without forcing a full view recalculation?Alternatively, is there a more efficient way to programmatically change the view

Hello everyone! My company uses Creo 7.0.9. I am utilizing J-Link (Java Object Toolkit free) to create some programs to automate some repetitive tasks. I need your help in automating the running of predefined FEA simulations, or at least fixing my code so far..._______________________________________________________________________________________________Problem Background / Goal: One of the features I want to have in my J-Link programs is the ability to rerun predefined simulations from code... meaning I as the engineer set up everything from conditions to loads, and get the simulation all ready to go, and my J-Link application really just has to hit the run button. The use case here is: I have other already functioning j-link code to change parameters of loads, so the idea is in the future, I can have some automated way of testing 15 different loads, running the FEA each time, saving results, and maybe even making me a graphic or something like that... _____________________

Hi,I would like to simulate the vibration pipe stress with frequency response (FRA).The source of vibration came from motor in compressor that we know frequency input that simulate from 20 Hz to 100 Hz   Load Set- Internal pipe pressure 3 bar- gravity load- torque from compressor The steps 1. Static analysis with pressure and gravity2. Prestress Modal analysis using the above static analysis for prestress.3. Run Frequency response dynamics analysis with torque varies on frequency. Are these steps correct? However, on FRA I don't know the amplitude. How can I find this amplitude?Also, There are 2 loading load functions and base excitation. My understanding this simulate should do the base excitation due to there are vibration from the base that pipe connected. Is this correct?  Also, the what is the value in base excitation and how can I find the amplitude. And in the calculate that relative to Ground and Supports. What are different of this 2?&nb

Hi, I'm trying to assign my parts as Natural Rubber in Creo, but I couldn't find the rubber material in my Creo material library. Could you please help me with this?

Hi, I'm wondering that the value of Damping Coefficient (%) in dynamic analysis is same as Damping Ratio?If not same how can I find this value? Thank you.

how creo 7 works in thermal analisys in a steady state ? I mean as input for thermal load i've to consider Heat Flux (W/m^2). This means that load is time dependent. I use a load of 5000W/m^ 2 on a steel structure with 30mm thicknes and i get more than 170°c of temperature. Teoric calculation give me 21 °c after 20 seconds.Does creo consider Fourier time to get Steady State: t= Thickness^2/(Thermal Diffusivity) ? and if it consider that how does it calculate that. Because in material specification ther is not thermal diffusivity value.thanks for answering

I have added IEAC (Exclude elements autogem control) to my fixed constraint areas. Autogem mesh also reflects the IEAC control. However, in the solver output file, i still see a warning" Excluded elements may be needed near constrain". Is this normal ?

I am trying to run a Kinematic type analysis. I could not see the option to enable Termination Condition for the analysis in Kinematic type of analysis. How can I terminate the run after meeting a certain specified condition? Thanks!

The exact calculation of the bolt force in Simulate is only possible by means of contact analysis:

Hello,I’m working on a 2-speed transmission model in Creo Mechanism, and I need some help setting up the dynamic gear engagement behavior. The transmission has a neutral, 1st gear, and 2nd gear.I start the mechanism analysis in neutral condition.The input shaft is driven by a servo motor rotating at 1000 RPM.A second servo motor is used for gear shifting (e.g., a sliding collar or actuator).           In neutral, all gear connections should be disengaged.When the output shaft engages with 1st gear, only 1st gear should be active, others disengaged.Similarly, in 2nd gear, only the 2nd gear should engage.All this should happen in one continuous analysis, driven by:One input servo motor (rotating shaft),One shifting servo motor (for gear selection).How can I simulate this type of dynamic gear engagement/disengagement in Creo Mechanism using just one servo motor for input and another for gear shifting? 

Need help in simulating the internal, external gear pair. And the gear-2 here will move horizontally and engage with gear-1. Also, gear-2 should start rotating after teeth engagement with gear-1. I am interested in dynamic simulation in this case. Is this possible in Creo Mechanism MDO? Thanks for your help! 

I'm trying to  apply a thermal load to simulate a bolt preload (a similar technique as it used to be done in Pro/MECHANICA) in a simple two plate model. To model the bolt I made a beam idealization that connects two rigid links at the bolt ends (one for the head and the other for the thread). I created a global material for the plates with 0 [1/°C] thermal coefficient and then another material for the beam with 1.2e-3 [1/°C]. For thermal loads I'm using a temperature load increase to 100C and fixing the rigid links. After that, I run the static analysis but nothing happens.  This is the first time I'm attempting this approach for bolt modeling, I'll appreciate any help to understand what I'm doing wrong. Attached is the zip file with the assembly and creo parts for reference as well as an image with some description labels.
