Mathcad

Hello,   I have no idea why this isn't working. It says "can't evaluate to boolean". Could you help me please? I'm really stuck.  

Hello,    I'm trying to recreate a student's work presented in a paper and I just can't seem to get it to work. I've gone through as many of the posts here on this issue as I can but don't see many of the common errors (incorrect equal sign etc). Occasionally i'll see a stray typo and fix it, but I think may have been staring at this too long to see what's wrong with it.    Error message is "Too few initial conditions". Mathcad doesn't seem very flexible in trying to track down erros like this.   I really appreciate your time and assistance,   - T  

Hello, I want to change an existing Mathcad scheme of solving to another described in a flowchart.    I cannot.   I attached the Mathcad file where I try, and also the Flowchart that I want to implement.    

Good afternoon,   I have a multi-column txt file. I want to perform an operation on two fields. Each of them has the following layout: number/number (eg. 4/5 or 4/5). I need to extract the first character from both of them and then add (eg 4/5 and 4/6 ==> 4 + 5 = 9) The problem is that MathCAD 15 reads the field as mathematical operation and gives me 1.0 or some fraction. How could I import it as a text, pick two characters, convert to INT and then get the result?   The second issue with the data is that some parameters are given only every 4th row, not each of them (eg. needed PDOP). I need to perform a simple statistic analysis (mean, stdev, min, max, med). As the columns with data (eg. PDOP) have empty rows I cannot do it.   I would be very grateful for your help. Perhaps @WernerE or @Werner_E  would have some advice for me. 🙂   Please find attached MathCAD worksheet and a sample of my datafile.

Now, not only W, I can use VA and Var for the units of electric power in Prime 6. 

As the title states I am trying to solve 4 equations simultaneously for unknowns.   I would like to solve for SM, KM, and RM.    I tired all sorts of things and now here I am, admitting I need help.     

I am trying to declare a variable based on a conditional, the following code is an idea that illustrates the intention:   import numpy as np a = 23 b = 54 c = 60 Qs = if a < b: Qs = 1 elif a < b < c: Qs = 1.4*a else: Qs = 0.69*b Best regards.

I am attempting to insert a file as reference inside another file. My undersatnding is that if I change a value in the reference file that value is automatically transferred to the other file. I do not fine that this occurs. The only way I get files to update is to go through the entire insert===> reference process again. Am I missing something ? I am attaching the files in question. Any help would be appreciated.

Dear Community,   as the Subject Title already refers to my question: How can i remove the last used file in Mathcad Prime 5.0?I've searched in the registry similiar to Mathcad 15.0 but unfortunately something like that does not exist? Is there a function/setting or something like that? I´ve added a screenshot of the mentioned last used files which i want to remove.   Would appreciate every helpful answer related to the topic.   TY

Hi,         I need to write a program to compare two matrices and eliminate non-identical rows. For example, please see attachment. In this case Matrix B can only contain numbers found in Matrix A. I need to compare each value of A with B and output values of B that matches with A (in the same order). Problem is some of the numbers in A do not appear in B and therefore, I am not able to use the match function. I would greatly appreciate any help.   Thanks.    

Can we create the formula of catenary using only Mathcad?  

When I try to open a file, I get this message. Looks like file has been corrupted for some reason. Can anyone help me recovering this file.

Hello,   I am doing this exercise about a combined cycle where some of the enthalpies are known.  The problem is when i try to solve the system the error "This variable is undefined" constantly appears. I have tried both of the systems i know about describing the solution:     Solution:=Find(x1,...) and (x)                                        (y)  :=Find(x1,...)   Hope there is solution. Thanks in advance. IG88   (Uploaded the .xmcd)  

Hi, Our service contract expired and I am trying to download 15 M030 but PTC does not allow it. What is the procedure to obtain the link? Thanks  

All, I did install the German version for Mathcad 15 M050. Starting the application I can only choose the English language. The German language is not present in the list to select in Tools>Preferences>Languages.

Dear all please create automatically Global Stiffness 6x6? as pic and attachment mathcad belowThank you  

From my (very limited) experience, in the (if, while) loop, Mathcad doesn't allow := but only <-. I was just wondering how are they differ from one another.   Thank you!

Hi All- I am attempting to model the first-order change of A --> B. The little programming loop below does the transformation of A to B in time steps of n just fine. The problem is I cannot view the A vs time data as is shown in the MathCAD document below. I know there are many other ways to solve this simple system, but getting this little programming loop to solve the problem is my goal.

Is there a way to fix this? I have a single-very large size of matrix(10 pages) and when I do anything within this matrix, it will start lagging.

How use Celsius here? Thanks!

I would like to create the digital double of  the yo-yo toy Were is my error? See please attachs MC15 & Prime 5. Do you know someone? Thank you!

I would like to calculate multiple values under one if statement. Right now, the only thing I know about if statement is that I have to assign if statement to a variable and that means I can only do one variable at a time. Please see below. For this example, if I would also like to compute some other variables other than SF under condition that d<=1/4 in, without creating another if statement, what can I do?   Thank you very much!   Edit: clarify question

Hello All, I am generating values for DEFORM FEA software to determine a sinusoidal motion. My current method is to develop the function for my motion in Mathcad, then take the variable value and transplant it into Excel.  From Excel I can copy and paste into my DEFORM table. I would like grab the values directly from Mathcad. Any suggestions would be appreciated! Thanks, Don

I am new to MathCAD and the following is what I would like to achieve. Would someone able to help me with this.      

Hi everybody! Is there anyone who can tell me what to do (or how to avoid the error) when, (MATHCAD 14 S. E.) with automatic calculation disabled, while saving, appears: "A generic error occurred in GDI +" and I can no longer save the file?
