Hi all,
I'm currently having some troubles analysing a beam (BEAM189)structure in ANSYS APDL 13.0. The problem is that I want to define some imperfections in the beam grid by adding displacements with the UPGEOM command, calculated in a earlier calculation.
After addition of the displacements, I try to solve and the analysis terminates with the following error:
*** ERROR *** CP = 2046.641 TIME= 11:48:29
Element @@@ integration 1 point is located outside of end stations.
Please verify section input 1.000007321.
When I minimize the imperfections to 1e-6 mm, the error does not occur. In my opinion, with this small imperfections I could neglect is at all.
Part of the code is added below
Could anyone push me in the right direction?
Thanks in advance
