Analysis

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:  

I am using Creo Simulate Release 9.0 and Datecode9.0.0.0Not converge for prescribed translationHere are the errors that I faced** Warning: Convergence was not obtained because the maximum           polynomial order of 4 was reached.

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. 

Here are 3 basic examples of Mechanism Dynamics

Hello,I'm trying to export *.gif files from a modal analysis, but the quality is extremely poor. The only available formats are *.avi and *.mpg — which is fine, I can convert them afterward — but the video quality is unacceptable.I don’t understand why I can export simulation images as *.jpeg in absurdly high resolution, yet when it comes to videos, the quality is so low. There are compression artifacts, text becomes unreadable, and any small details in the model are completely lost in a blur of pixels.Is there any way to improve the quality of exported video or gif files? 

I want to calculate the torsional stiffness for my design, So for that I have to determine the value of angle of twist in simulation. Can anyone tell me the procedure to calculate the torsional stiffness or angle of twist in creo simulation.

Hello,I would like to know if annotations can be exported inside of simulate result *.pvs file.We use *.pvs results very ofter but not all people in our company use creo simulate. So when there are many hydraulic cylinders and report doesn't have any reference of which one is which it is pretty hard to find excel reference in *.pvs model.How can i define a note which will be exported to *.pvs file where each hydraulic cylinder will have it's personal note.Expected output: 

Hello community, I've been researching the possibility to plug in the output from Creo Mold Simulation (Warpage & Fiber Orientation) into Creo Simulate. It seems PTC hasn't created that capability and they seem to be suspiciously silent about it, either due to the complexity to implement it or lack of knowledge on how powerful this could be for our design and analysis, as they seem to have everything on hand to add this feature. If someone knows a solution or workaround to use CMA and Simulate together let me know. Thanks!,JD

Hi communityI am interested in simulating the separation of bodies. In effect, I am tearing one body from the other.The two bodies have different materials, and bonded contact between the bodies.I create the separation using displacement constraint. In this situation, the elements continue to be connected between the bodies and do not "disconnect" during the separation process. What am I doing wrong?Does anyone have a recommendation on how to simulate this? Thanks in advance.

Hello! I would like to ask the community about the mesh validation. There is a tool for it in CREO Simulate that is useless for a big simulation models (100000+ elements) it is impossible to turn the model while the mesh is displayed. So is there any feature or tool that will help to hide the valid elements and show only bad elements on the screen. Thank you for the response!

Hello, I've been trying to find those files all around Windchill and my local PC but didn't succeed in that. Where does creo simulate save mesh files?
