The OpenSees Community

Sorry for the double post. I discovered the source of the problem: using num_fiby x num_fibz = 100 x 99 [or less] runs without problem. Using 100 x 100 fibers crashes...

upd: OpenSees crashes right after the 1st step of the Lateral Loads analysis, whatever loads I apply. If I write "analyze 1" there is no problem.
Any ideas ?

Thank you Dr. Mc Kenna for your reply. The problem is caused by the fiber Section OR/AND Section Aggregator, with an elastic 3D section works fine. I tried all the possible ways to create a fiber Section [patch rect, patch quad] and all kinds of elements [forceBeam, nonlinearBeam etc] I tried also t...

This error message appears with every pattern I tried, before the beginning of the analysis [dead loads have no issue]. The weird thing is that opensees.exe stops working.

Hi everyone. I'm trying to impose displacement pattern at a cantilever's (3d - 6 dofs) free end : pattern Plain 2 "Series -dt $dt -filePath $filename -factor $factor" { sp 2 1 1.0 } The integrator is LoadControl, and I use constraints "Penalty". I am getting the error message: &q...

Try using Concrete02 material instead of Concrete01, but be careful with your model... I have issues applying Concrete02 with some combinations of GPs per element, sub elements etc ... I realized that using more elements or more G.P per element may cause premature failure.

Same issue (2-stories frame) with Concrete02, works fine with 01. Any suggestion?

Thank you fmk! So, "reset" command doesn't wipe previous results?

I' m trying to execute a parametrical push-over (for example different axial load each time), so a loop is needed. I 'm having problem at the end of the first loop, where I must wipe last's analysis results, close recorders and proceed to the next loop... I tried "remove recorders" or/and ...
