I’m trying to express the solution in mmHg as a unit for pressure. Is there any way to do this? 

Hello,I just started using MathCAD Prime 3.0 and stumbled upon a problem. I can't find a solution to that online.I have a question about this screenshot:Why appending a result to a variable makes the operation impossible (1st and 2nd columns)?Why showing the value of a variable makes the next operation impossible (1st and 3rd columns)?Thank you. (I hope this post is in compliance with the policy)

I’m using MathCAD Prime 9.0.0.0 and I’m running into a units error…All of the R units should be K/W, but I’m getting crazy units especially on Rmid. I attached my program as well as lecture notes that show how to do this. Look on page 44-45. Thanks,    Brent

I am trying to compute the equivalent annual percentage rate (APR) for a series of variable deposits with variable returns.Using the “find” function results in the error message “No solution was found...”. I tried opening up the TOL value, that didn’t help. So I tried the “minerr” function next and a different error message is displayed “Indexed assignment...”, My questions are:Which of the two errors is relevant? Can I solve equations with indexed constraints in a solve block?MP11 file is attached.Thanks for your help,

 I recently started using Mathcad Prime 12 for structural engineering / Eurocode calculations and I noticed something frustrating regarding the unit system.Mathcad correctly understands that: kg/s² = N/m. However when working with line loads (common in structural engineering), Prime often displays results as “kg/s²” instead of the expected engineering SI unit: N/m or kN/m.The strange part is that under “Insert Derived Units → Force per Length” there are several imperial units available: kpi, klf, plf. but there is NO SI alternative such as N/m or kN/m.This creates a awkward workflow in SI-based calculations, especially for Eurocode and structural design where line loads are constantly used.Currently the only workaround that i found seems to be manually dividing by (kN/m) , creating display variables or manually writing the unit as text. This partly defeats the purpose of the otherwise very capable engineering unit system.Questions:Is there any hidden way to add custom SI derived units

Have a good day, community. I have a problem with solving a vector-type equation. The issue is that the solution only returns the last result, ignoring the previous calculations. Could someone please help me? I’m uploading the file in Mathcad Prime V.10. 

HI i dont know who i cant convert the file from xmcd to mcdx. can some kind soul help me to convert it ?

Hi, I am trying to solve an ODE to model a “Ball and Cone” tuned mass damper. The equations simulate a ball mounted inside a pair of cones with mass on top. The ball oscillates up and down an inclined slope with a curved region at the apex between the up/down slopes. I am using Radau solver as it is a stiff equation. Adams/BDF “does not converge”. The 1st solve block uses a simplified simulation for base excitation of the TMD. Using Radau with modest levels of damping the first solve block result gives a discontinuous response which should not happen given the inclined slope is a tangent to the curved section at the apex. Any ideas how I can correct this discontinuity would be appreciated.I tried using sigmoid transition functions (2nd solve block) for the step between inclined slope and radius but this gives a large number error.The 3rd solve block includes an extra degree of freedom to simulate the tower on which the damper is mounted, which is the aim of the program. This won’t solv

how can we convert xmcd files if converter is not working, is this a bug any workarounds?

Hello,  Moving to Mathcad Prime 9 from V15, and noticed there are no rules or guidelines to align the different regions of the document. Any suggestions/tips/tricks to align the regions other by eyeballing them?

Snapping to the grid is not a good alternative to being able to align a group of regions.  It was very easy in Mathcad 15.  

I am trying Prrime for the first time today. How do you align regions vertically? I know how to do it in M15, but I can not figure out how to do it in Prime. I also can not find in the help guide.Thanks Andrew

Hi, I recently changed the motherboard on my PC, and my Mathcad15 licence is no longer valid. Impossible to tranfer it to a new host ID, PTC does not recognise it. I have Mathcad prime 3.1 licence, working well, but the converter from .xmcd to mcdx does work without Mathcad 15 operating. I need only 6 files to be converted.My question is if anybody having Mathcad 15 and Mathcad prime 3.1 installed could kindly do this conversion for me.I join a ZIP with the filesNote that Prime 3.1 version is required, More recent versions might deliver .mcdx files not readable with 3.1 version. I’ve read that somewhere on this siteThanks in advance 

Trying to solve a large linear algebra Ax=b problem using Prime.The x:=lsolve(A,b) says not enough memory, but I can solve the same size using other software on my large 128GB of RAM.Prime 11 reports in task manager as only 217 MB.How do I give Prime access to more memory if possible?Cheers
