hello im solving the equation at the end .But i dont want that unknown variable to be marked in red colour how to solve this problem.

Hi all,

I have built a calculation sheet that is dependent on some rather large data tables. I have used the Insert > File Input method to reference these tables. This works fine for building the sheet, but once I distribute it to 100+ engineers, I feel like there will be an issue with having to lug around several data tables.

I found a semi-solution on here that mentioned defining a variable, and copy-pasting the table there. However, this makes the data tables cumbersome. It's also messing up my vlookups.

Is there a way I can integrate these tables into mathcad the same way one would with a insert > file input method, but without having to become dependent on external files? Perhaps there is a way I can integrate the data directly into my mathcad sheet?

Thank you.

Hello,

I am completely new to this forum and I have 2 questions. I tried searching the discussions

for the answers but I was not able to find the complete answers.

Please excuse me if I missed something.

I would very much appreacite it if someone could help me with the following :

1. We recently started using MathCad 15. We soon realized that we needed a 64 bit version of the tool.

According to what I read, I understand that MathCad 15 cannot be invoked in 64 bit more.

Is this correct ?

2. To solve the problem above I installed Mathcad Prime 3 on the computer which also has Mathcad 15.

Both versions presently coexist on this computer. I tried loading an xcmd file into Mathcad Prime 3 and

got a message saying that I first had top convert the file to MCD format using the converter button on the

the Input/Output tab on the ribbon. Unfortunately, this tab is DISABLED (not highlighted) and so I cannot

invoke it.

I read in one discussion that for this to work, both Mathcad 15 and Mathcad Prime 3 had to be installed on

the same computer. This is exactly what I have.

I would appreciate it very much if someone could explain to me how to overcome this problem.

Thank you so much for all your help,

Goel

I have a main equation formed by a sub equation with two variables of interest (AA and BB), plus a third (D) that can not be cleared, so I solve by iteration with the help of the Given and Find commands.

My question is whether it is possible to direct the main equation as a function of AA and BB, and according to the values that take these, calculate the variable "D" per iteration. Attached is an example for clarity of the problem I have and what I want to do.

Thank you

We have previously built a MathCAD wrapper for the CoolProp (www.coolprop.org) library of fluid properties.

I am rebuilding the wrapper for the new version of our library, and I was wondering what versions a custom function built for Prime 3.0 would be compatible with. Would it be compatible with MathCAD 15.0? Has the ABI changed since 15.0?

I am building an updated wrapper of our library (www.coolprop.org) for MathCAD.

My question is very simple. Am I allowed to include MCADINCL.H and mcaduser.lib in my source code repository according to the MathCAD license terms?

I would rather not have to deal with finding the right path for these files at build time if it can be avoided. We use CMake, so it is possible to find the right path if needed.

Hello everyone

I'm trying to extract values for certain variables from multiple tables based on a data table to perform operations with the values of interest.

Attached is a file in which I show what I try to achieve

Thanks in advance

I am working through this tutorial (from this site), using Mathcad Prime 3.0, F000 The thing that is driving me absolutely crazy is tha tI can't get it to solve symbolically, like the tutorial says it should.

I am trying to do this problem:

However, when I insert the symbolic operator, this is what happens:

Why am I getting a numeric solution instead of a symbolic one? It's especially frustrating since one would thing a PTC-supplied worksheet would, you know, work.

Any input is appreciated.

Thanks.

Hello there,

I have try to calculate a volume of a torus, and for that I use a function of z and two integrals, but I got error "unknown error".

I believe my formula is right, also expression.

You can check attaeched document.

It works in cylindrical coords, but I also have to calculate in cartezian . What I'm doing wrong?

regards, LL

There was a useful collection of worksheets available until recently with a wide selection of topics in engineering: Civil, Electrical, thermodynamics, physics and mathematics, but suddenly it is no longer available. Withdrawing a library with the perception of profit making is the short-term narrow mindness of salesman instead of fostering the use of Mathcad for the long term which is what Mathworks has been sucessfully doing with its well established product Matlab.

I need to convert mathcad 15 results having mm to fractions inches using scriptable objects)

Hi,

I have tried to do some fixed-step equation solving for power converters, and I have encountered a very weird phenomenon : a unit assigned to "0" without being asked.

here is a file that reproduces the problem. The "physical" model is a boundary-mode buck converter. The switch is on (PWM=1) for a fixed duration (ton), then off (PWM=0) until the current in the inductor reaches 0.

When the PWM is set to 1, no problem, but when it is set to 0, Mathcad strangely sets it to 0s. If I specify a unit, this units "overrides" the s. If a unit is set to the "1" condition, it applies automatically to the "0" condition too (???). The only way I have found to get rid of this is to do PWM:=PWM/SIUnitsOf(PWM), but it would be much better if it didn't force some unwanted unit in the first place.

Any idea where that comes from, and how to prevent that from happening ?

Thanks
