(OP)
Hi all,
I am really struggling with something for a couple of days now.  I have a model and I am trying to restart it using the import analysis.  I have to do this since I wish to change BCs and hence cannot use a restart analysis.  Some of the model has 3D brick elements, some continuum shell.  The import facilty works, and the new analysis initial step corresponds to the results of the last increment from the previous analysis.
However, I soon get excessive deformation in the continuum shell elements, as if the stacking direction is no longer as it should be (these are continnuum shell composite sections).  What am I doing wrong?
