Fixed Restrains not writted in the input file

[Serchu]

Hi, I'm trying to make a FEA using TIE to keep joined two parts of an assemblie. In order to generate the groups what I make is put fixed constrains in Freecad and then manually edit the input file to remove it and transform to SURFACES and then apply the TIE command. Problem is that some constrains are not writted in the input file, it generate the FemConstraintFixed, FemConstraintFixed001, skip the 002 and 003, and writtes the 004 and 005.

Any suggestion of what can be wrong? I'm attaching the file if somebody has time to see it. By the way, the Define Node /Element Sets option works? I cannot define the sets in this way.

AFAIK at the moment writing force and fix constraints to the calculix input file is supported only for one FEMMesh in the analysis. If there are more Meshes they are not used to find the node sets. That is probably why some fixed constraints are empty in the input file because the nodes where not found.

Here we are: https://github.com/FreeCAD/FreeCAD/blob ... ls.py#L133

The first FEM Mesh which is found in the Analysis will be taken. All other will be ignored
