FEM static calculix big modell No nodes found in Frd file

Post by skull »

Hello.
I have aFEM Static model with two arrays of rails.
With 4 Ellements all is fine.
I get with 9 ellements: No nodes found in Frd file :

11:46:00 FEM: No nodes found in Frd file.
11:46:00 Problem on frd file import. No nodes found in frd file.
11:46:00 FEM: No result object in active Analysis.
1:46:00 Read ccx results from dat file: /tmp/fcfem_mlh0b7ym/FEMMeshNetgen.dat
cat /tmp/fcfem_mlh0b7ym/FEMMeshNetgen.dat
gives nothing back.
I used netgen and calculix in standert mode.

11:55:46  Nodes, but no results found in frd file. It means there only is a mesh but no results in frd file. Usually this happens for: 
- analysis type 'NOANALYSIS'
- if CalculiX returned no results (happens on nonpositive jacobian determinant in at least one element)
- just no frd results where requestet in input file (neither 'node file' nor 'el file' in output section')
