Problems with non-linear analysis in Ansys 15 Mechanical APDL
Problems with non-linear analysis in Ansys 15 Mechanical APDL
(OP)
Hey, my problem occurs when trying to perform non-linear structural analysis for Shell 181 model in new Ansys 15. The thing is that the same analysis goes correctly for previous Ansys version (e.g. Ansys 12). However, Ansys 15 doesn't obtain convergence and the solution is made approximately only halfway.
I use typical solver options:
ANTYPE,0
NLGEOM,1
NSUBST,100,105,100
OUTRES,ERASE
OUTRES,ALL,ALL
solve
I am trying to use different solver such as Sparse,PCG,JCG however it still doesn't work. Have you ever met with such a problem, do you know what can be the reason? Probably some solver default options changed in Ansys 15 and I do know which of them. If you have any idea please share.
