Mathcad

Hi guys! I am a totally beginner in MathCAD and trying to solve a system of two equations.   On one hand I have volume as a function of Pressure (V=f(Ps)) and other known parameters. Then I have two equations of compressor Head, one as a function of Ps (and other known parameters) and the other as a function of Volume again. So I could equal both equations of Head and have one equation with two variables V and Ps.   The thing is I can't find how to find Ps and/or V to satisfy the equations... Many thanks.

is it possible that explicit shows only numbers and short numbers like 2-3 digits

Hallo,   a repating question about Prime 5.   Has the all new Mathcad now ALL Features of the loving Mathcad 15?   Then i will test it in my company to suggest it.   The new optic and the possibility to make a text area with WORD functionality looks good to me.   lg Stefan

In Mathcad 15 it takes one minute to open excel component... with office 365 In old version it took 1 sec. Very frustrating, Any solution? Thank you

Hi I want to make a vector calculation problem, and i want make a graph for representation for solve my problem For this, i need to hash a range on axis Example: For x axis I define xmin:-10mm I define xmax:10mm I define xstep:0.5mm I want to make a program for define a matrix that include all value. Program must be return -10 -9.5 -9 .... 9 9.5 10 This for XYZ translation and RxRyRz rotation Do you can to help me ? Thanks

Can we change the font style in the area title?

Hallo   i just installed mathcad express but i cannot convert files. The symbol is greyed out.   Can aynone help me?   lg Stefan

Hello everyone,   I am getting the following error when trying to run Mathcad with my .dat license. I have tried running the wizard and selecting the .dat I originally had. I also tried the .txt file that I got emailed to me when i "retrieved my license" on the PTC website. Has anyone else encountered this issue? I am not very familiar with this program so I apologize if this seems simple.   Thanks, Rob

Hello,  I have been trying to solve this problem below using MathCAD. Yet I could not do it. Kinda stuck in here.

After working on a Mathcad file for more than 2 months and for a design job I am doing, I tried to open the file today, but it won't open at all.I tried from several computers.Every time I get a message saying:The file type is not supported. Log file is located at...etcI have not updated the tile type. So obviously the software corrupted the file last time it was saving it or so.Now how do I retrieve 2 months worth of work?I was going to negotiate with my management to upgrade to a paid version of Mathcad and use it as the standard tool for all our calculations. But now I don't trust it.Please advise how to retrieve the file contents.thanks

Hallo,   found something strange in the calculation when i show all decimalpositions   Is there any plausible explanation?   lg Stefan

Hi,   I am using Mathcad 15. Usually I will copy and paste drawing from autocad to Mathcad worksheet. Then, when I right click the Autocad drawing in my mathcad worksheet, it only have option edit DWGTrueView object but cannot edit it with DWGTrueView.    Can someone please show how to edit the Autocad drawing embedded in Mathcad using autocad? You can review the attachment.   Thank you

Does the newest version - Mathcad Prime 5 has the option of formating as it was in  Mathcad 15? Mainly I have in mind these options: definition as equalevaluation as equalhide keywords    

Hi, I am trying to do this workshop as shown in the attached picture. I am a new user to MathCAD and it needs to be done using MathCAD. It is an iterative calculation to find parameters related to the terminal velocity in a settling equation. In this case, the desired terminal velocity of the particle is known, I am trying to find what the associated diameter D for that velocity would be, given a certain particle density p_subp. Reynolds number is R, Drag coefficient is C, as defined by the equations in the picture. you can rearrange the velocity equation in terms of v or D as desired. The physics part is easy but I am having the following issues.   Since C is a piecewise function based on value of R, I have used if/else statements to determine value. However, MathCAD highlights the inequality Re<1 for C <-- if Re <1 and says "This value must be a scalar" This also comes up for the R<1000, R<200000 terms. Any fix for this? If that can be fixed, it is part of a

Hello, I am trying to control the output of the trace() function for debugging. Ideally I will want something like the fprintf function of several programming language to control the characters that the output displays. It becomes really cumbersome to read the output if the vectors are not aligned as for instance   What I would like Iteration 1 vec1_vector(3) [1.0000e-06, 0.0000e00 , 0.0000e00 ]  __vec2 vector(3) [0.0000e00 , 0.0000e00 ,  0.0000e00 ] Iteration 2 vec1_vector(3) [1.6667e-06, 0.0000e00 , 1.3413e-02]  __vec2 vector(3) [0.0000e00 , 1.3413e-01, 1.3413e-01] Iteration 3 vec1_vector(3) [1.6667e-06, 2.4513e-01, 1.3413e-02]  __vec2 vector(3) [2.4245e-01, 1.3413e-01, 1.3413e-01]     What I am getting Iteration 1 vec1_vector(3) [1e-06, 0, 0]  __vec2 vector(3) [0, 0, 0] Iteration 2 vec1_vector(3) [1.16666666666667e-06, 0, 0.013413413]  __vec2 vector(3)&nb

how can i change page number in footer and delete "of" or change "of" to "-" there are words "page" and "of"   but i want to change to other language..  

Hallo,   question about the new Prime 5.0.   As so far we are importing loadcases frome excel calculating the stuff and exporting the results to excel.  After calculating the loadcases we are creating a calculation report in WORD. Copying the excel table and the mathcad calculation in. Now our reports have up to 500 Pages because one calculation can have up to 30 pages.    Now is Prime 5.0 capable of doing such a Report of 200 to 500 Pages? So there is no need to use Microsoft Word anymoore?   Or are there any limitations like in Mathcad 15 where there comes always the message not enough working storage.   lg Stefan

Hello everyone!Why is the generalized integral, highlighted in the figure, null? when, instead, should it be 1?Thank you very muchGreetings F. M.

I have defined a load function, which plots nicely:   Then I find the shear force diagram by integrating the load function and considering reactions.  This also plots nicely:   Finally, I want to find the moment diagram... should be just an integration of the shear force diagram... but Mathcad seems to get confused: (100kNm is just an estimate for demonstration purposes) (Note the single point at 0, 100)   Am I doing something wrong, or is this a Mathcad problem?   The main source of my frustration is that the loading diagram 'works' and the shear force diagram which is based on it, also 'works' - why then not the bending moment?   Although I understand that posting the calculation file is preferred, I have not done so as it is over 25 pages long and almost every page feeds into these functions, eventually.  Would anyone have any ideas of what I should check?    

Plz check the mathcad file.
