Mathcad

Can anyone help me figure out why my mathcad sheet won't solve? I tried inputting a guess value and solving with the Find function to no avail.

Hi, I have a 3d plot on an rectangle range within x-y, I want to have a 2d slice view of the diagonal. Is there a way to achieve this ?

Hi, everyone,The function I am going to plot has two sets within the range x:(0,1) and y: (0,1),when the square is split into two triangular.But the loop I write only plot the latter set that I wrote.So how to plot both of them?Looking forward to hear from you!BestShawn

hello folks,when right clicking on a textbox one can chose on the fonts tab a text effect called "underline". I'd like to access and control this via a program. However, this method is not listed in the developers reference the Textbox Format Properties. Does anybody know whether this can be accessed by some other property or method?Thanks in advanceRaikoP.S.It goes without saying that I'm using MC15

Hello!i have some problems with the calculation of slope.In my calculation I would like to define the slope in %, and calculate in the furhter sheet with the correct result in degrees (e.g. 100% slope should be 45°).But my problem is, If I define:slope:=100%and try to change in the next step to get the result with unit ° or deg, but i get:slope=57.296°Is there anyone who knows the problem and the solution for this topic?Many thanks in advance!Paul

Does anyone like Prime 3.1? Does it offer any benefit over MC14?Thanks

Anyone tried out the Dell Performance Optimizer?Dell is very secretive about what it actually does - you won't find details in any of the documentation or the software. The Creo profile, for example, disables hyperthreading (good) and disables 2 CPU cores (bad if you're also a Mechanica, Ansys, etc. user). There are some other things it says it does for Creo but it uses fancy language without actually telling you what it is changing.They say you can have multiple profiles active. I have no idea how it manages conflicts (e.g. Creo disables HT and 2 cores, while Adobe Creative Suite probably activates HT and all 4 cores) because someoptimizations conflict andcan't bechanged without rebooting.They don't have profiles for Mechanica, Ansys, Mathcad, etc. There's no way for you to create your own profile.Maybe it makes sense if you're a single application user. But people who are trying to tweak an extra few percent out of their machine probably know what to change anynow. If you use a CPU-i

I have created a sheet and come to the end where I now need some help with a routine I believe. I have a thickness variable titled t.g and the corresponding Performance Ratios shown next to those thicknesses. The columns represent the grades of steel I am using. Now i need a routine to look through all three matrices and find the first instance of when all three have a value of 1.0 or greater. When that occurs I would like it to output what thickness and what grade of steel that corresponds to. Attached is my sheet. Any help would be greatly appreciated.

Hi, I'm trying to practice using the Find function, and using a workaround with units.Pls. see attached. The units are working but the answer it found is wrong. "Io" is supposed to be 4.

Does MathCAD Prime 3.0 come with MathCAD 15? I can't seem to find this information anywhere on the PTC website.

HiIs it possible to have results to change color depending on the resulting value?As attached is a sheet describing the question.Thanks for help.

I have a series of equations to solve with range variables but I get a "This variable is undefined." error when using the Given/Find solve boxI have attached the Test worksheet and the original worksheet that demonstrates it works for a single variable

I have an evaluation copy of Prime 3.1 and the file converter crashes for me. Anyone know how to fix this?

I have a single user Mathcad 15 license. I uninstalled Mathcad 15 from my old computer and installed it on my new computer. Every few days I get a message "sw_license_email_1173070.dat does not exist." It asks me if I want to open the license wizard? I say yes and I supposedly get a new license except the file never appears and a few days later I get the same message. I have a file sw_license_email_1826767 that was apparently created when I installed Mathcad 15, but that is not the file being searched for. Apparently I am limited to online help. I have tried creating a new license file, but the hostid format always seems to be wrong. Various places have said it is the C: drive serial number or the MAC address of he ethernet adapter, but the format is always rejected as wrong without telling what the right format is. Apparently you cannot get technical help without a maintenance contract. I am not trilled about paying a software company extra to fix its bugs.

I used MC15M030 to solving an optimitization problem, and I defined ALL >= 0, all the variable large or equal to zero. I have used 4 methods to do it in a same Maximize Solveblock, but I have got 3 different result.   Look at the pictures below: the result of (1) and (2) are same and right.   (3) and (4) are different and wrong. How to explain this puzzle?

Can someone help me with this loop? I cannot seem to get the loop working for the for statement

Hi guys I am still learning the ptc mathcad software. I am trying to use trial and error to find the solution of depth (Y) in open channels using mathcad solver block. I have set all guess values and constraints, how best can I solve this? Or is there another way of determining the value of Y. I have also attached the original question with step by step calculations and correct answers, in case one needs to restart everything. I appreciate your input and comments. Thank you in advance.

I have the following fairly simple equation. When I use the solve it say no solution was found but I can iteratively find a solution myself?

I am sure I am missing something but...I want to multiple two vectors... Say, a vector of molecular weights times an equal length vector of component molar flow rates to produce a vector of component mass flow rates.If I simply multiply the two vectors in MCP3.1, I get a scalar which is the sum of the products (in the example above it would be the total mass flow for the stream).But how do I generate a vector where each element is the product of a mwt times a molar flow?[I did look at the vector operators and functions but none of them seemed to do it.]TIA--Doug

Is it possible for Mathcad Prime to integrate a piece wise function? In the attached worksheet I am attempting to integrate a piece-wise function 4 times. If possible I'd like to be able to create a graph of these functions and then pull values from the graph.
