• Thanks a lot JohnM! I do seem to get convergence even for an extremly low tangent modulus when applying a deflection (for a ramped up load load and a higher tangent modulus it also converges). In both cases it seems clear that post elastic buckling…

• Thanks JohnM! I take it you mean that the load introduction area/zone should be sufficienlty stiff to avoid issues there? I have noticed that the tangent modulus greatly affects the convergence, esp. that the lower it gets the harder to get converg…

• Hi Victor, Thank you very much for the quick reply and your valid pointers! I agree there are more things to consider, like imperfections, internal stresses, load introduction (which is a bit more complicated than explained) etc. A run with coarse…

• "Problem" solved, garbage behind the keyboard - missed to add the configuration name (loadcase) to the file name in the custom model definition, e.g. "filename_LC1.frd"

• Hi, trying sub-modeling on a more complicated model (using Mecway 13, ccx 2.16 pardiso which worked fine on simpler models) but keep getting this error message: ERROR in readfrd: The input file "coarse.frd" could not be opened. *ERROR in u_calloc…

• Thanks again JohnM! I actually got some simple models to work, but as you mentioned, did only work with older ccx.exe (I used version 2.10)

• Thanks a lot JohnM! I will try that out, even though I think it's way above my current skill level, as I'm mostly using Mecway "as it is".
