Unknown error when solving DEs

[flix]

Hi all,

I am a mathcad-noob, started using it today. I use ptc's eLearning library to get to know the software. However, in the section about solving differential equations I have run into a problem:

As before, I do everything like it is written in the eLearning article. But when I want to solve the DE using odesolve, I get an unknown error: dae%_initial%_condition%_error (See attached pic for more info).

Who can help me? Couldn't find anything of the sort here or anywhere else on the web.

Thanks a lot, Felix

Hi Valery,

Cheers, Felix

Sorry, I can not find an error in your sheet. May be the point is in lables of variables and functions. I can only rewrite your sheet without errors.

I think that tools for solving differential equations in Mathcad Prime 1.0 are very... unpolished. And I do not recommend using them. We have to wait what will happen in the new version of Mathcad Prime.

Hmm, unlucky me then! 🙂 I will have a look at it again, maybe something springs to my eye. thank you for your help!
