Hello!
I have a model consisting of RC frames and masonry infills for which a try to run a static tim-history analysis. Unfortunately I can't run the analysis because at one pont I receive the max_tol error and after that the analysis stops. For concrete I use the con_tl model and for steel the stl_mp model. Could anyone take a look at the model and tell me if there are errors in it?

Hi Florin,

The implementation of infill panels in RC frames can cause significant changes in the structures behaviour that may lead to a premature failure of your RC elements.
You can verify (e.g. defining some performance criteria) if your material strains at the "collapse" reach its maximum capacity before the analysis stops.
This way you can control if the numerical instability is not the result of the structures collapse.

Cheers,
Romain
