I need to solve a system of two PDE with complex coefficients.Please, can you specify a PDE solver which works with complex coefficients, or send me a link to the tutorial. thank you,Oleg

Does anyone know how to save the state of a listbox in Prime 10? I know how in v15, but cannot get it to work in Prime. When a worksheet is closed and reopened, the list boxes all reset to the top line, not the choice that was made. I agree a lot of improvements have been made with Prime, but this needs to be addressed. 

I would like to help the company I work for solve the problem of Mathcad 15 to Mathcad prime 8 conversions. However, this turns out to be a big problem because the same variable is not used in different formatting during the conversion and Mathcad prime then does something that destroys the calculation. Can someone please help me here. I put some exmple files under this.

Dear Sir,I would like to inquire if Mathcad Prime has the option to set different headers and footers for the first page and subsequent pages.Your guidance on whether this functionality exists and how to enable it, if available, would be greatly appreciated.Thank you for your time and assistance. Ikbal

I need to move my license for Mathcad 14 from my old laptop to a new one so need to get a new license file. How do I go about doing that? when I tried to open a case they referred me to this site. Thank you!

Dear all users/Sir,I would like to know if it is possible to open Mathcad Prime files in multiple windows. Whenever I open a new file, it appears in the same window. Having the option to open files in separate windows would make it much more convenient to work on multiple files simultaneously. Your guidance on this matter would be greatly appreciated. Thank you for your time and assistance. Ikbal

Plotting a graph with Chart_Component is giving me an error, but insert plot allows me to plot chat with ease. What is causing this error? Kindly help and suggest me a better way to plot if possible.Also, kindly guide me on how to plot a tangent to a prior plotted graph.Kindly find the attached document below.Thanks and regards.MSRAZA 

For s=10*10^-9 and T =293, I obtain two different values of V_mag. Why? The mcdx file is attached herewith. pls help. I know the correct answer is -0.261 for V_mag.  I wanna plot V_mag/k*T with s later on.

I formatted my PC and I want to reinstall Mathcad Prime 9 because I have a license but it won't let me activate the product, what can I do? ----------------------------------------------------------------------------Translated the topic from Spanish to English using google translate - Subject - Como volver a activar una licencia que tengoBody - Yo realice un formateo a mi pc y quiero volver a instalar mathcad prime 9 porque cuento con una licencia pero no me deja activar el producto, que puedo hacer?-By Community Moderation Team---------------------------------------------------------------------------- 

There was a problem installing the application. The first time I installed it and worked in it. Then the application disappeared from the computer by itself. When you try to download it back (it shows what has been downloaded), it does not appear on the computer.

Currently have PTC Mathcad 14 on my old machine and i downloaded mathcard 15. i tried to transfer the License.DAT file from old to new and it says there's a problem. i re-run the wizard and select the license.DAT file and it says import successfull or something to that effect. i close the window and re-launch the program and get the same issue.. I tried installing mathcard 14 and did same thing and get same issue. i'm trying to retire my old computer and put it on the new updated system.please advise.

I hope everyone is doing well. While plotting a graph, I receive an error.Please assist me in fixing the issue.Please find the attached document below. Thanks and regards.MSRAZA.  

This is the function I need to reach  f1 and qc are matrics >> so I define another variable nthen I define M(a,b) to multiple dz by n then I define Mi,north to multiple qc by n Then I get the results equal to NaN  So I used filterNaN function  and after doing all of this >> I didn't get the answer hhhhhhIs there any away I can simplify the function I want, and get the answer The sheet is too long this , I couldn't explain what I need in shorter sheet>> sorry  page 19 prime 10 

Hi there ,I have a nested variable called x =[k v m] as shown in the screen shotI need to divide x by n  which means that each row in x will be divided by n >>> so k/n , v/n, and m/n>>>> the result should look like xThanks in advance

Hello All, I am trying to recreate the solutions in Prime 10 to a 'characteristic equation' from a technical paper involving the Bessel functions.The equation to be solved is shown belowThe first 10 solutions is given as: However it appears that the solve block essentially just returns my inputs  I have removed all units as I recall in the older versions of Prime that units in the solve block tend result in errors. I have never had to use the Bessel functions, so I am not sure if I am overlooking something or making a simple error given how the equation is stated. Can anyone review and provide some guidance ?

Team, Does anyone have a Mathcad Prime routine to calculate the unsigned Stirling numbers of the first kind? Thanks,Glen Atlas, MD

I need to choose the minimum value of q depending on the layer thickness...If the layer thickness is =< 2m the q should be the minimum value of ( q;avg or 12MPa) if the layer thickness is > 2m q should be the minimum value of ( q;avg or 15MPa) I tried to do it this way, but it is not working.  Can you spot the mistake in this , please?Thanks in advanceYusra Prime 9 page 12

Hi How do I put units into a slider? Thank you

I am getting error for unit compatibility while solving equations using solve_block. Please guide me to make correction. thanks.

Hi ,@Werner_E Can we modify this function... below the program finds the average of all qs of CPTs in one layer.... Iike if we have 10 cpts each one has 100 qs in one layer ..it sums all the cpts and finds the q of all of them in one layer..   What I need  now is to find the average q value of each CPT separately in each layer ..like each brown line in the plot alone .. Can you help me with that .?.I attached the same sheet you used previously in the thread. Thanks in advance 

Hello Community, I'm pretty new to Mathcad, so I'm sure I'm just missing something quite basic and obvious. What I'm trying to achieve is to use the results returned by the match function, to extract the equivalent rows from another variable. Given variable A and var. B use the match function to find the row index for values greater or equal to 2.5 in B, and use those indexes to create a new var. containing the values in A for the indexes (or just print directly from A). The result I was expecting was the new variable to return "Ac" and "Ad".  I originally thought it should be a fairly easy task, something like the shown in "Approach 03" of the screenshot.However, I'm finding all sort of errors when trying different approaches. The more predominant error bein: "This value must be and integer" Any help, please? Thanks! 🙂 

Hi there, I think almost 30% of mathcad's community questions is about ( this value must be scalar) .. I really find it confusing to differentiate between scalar/ array/ vector( maybe it seems stupid to you, but can you tell me how to identify each one of them? and the errors occur because of themI got this error in my sheet, how can I solve it ?prime 10 is attachedThanks in advance
