"experimental" solver and py3/ Qt5

[Jee-Bee]

Hello i have downloaded the windows conda py3Qt5 build. Since these don't have GMSH or calculix i use the calculix from other version(py2).
This works well with default ccx solver. but not with the "experimental" one. I get this error. I guess it has something to do with py3 or Qt5? can somebody confirm?

Code: Select all

It is not the experimental solver you are talking about (this is just the mune entry). It is about the solver framework solver ccx. Just gave it a try too on

I can confirm the following problem:

If you try in Task Panel you will see file writing works well, but ccx can not be run. Z88 and Elmer solver framework solver have similar problems.

Seams noone has ever used the solver framework solver on Py3.
