Dear forum,
I would like to release some DOF of the supports after an initial form finding analysis before I go on with the rest of my simulation.
When I use SOFIMSHA I can not release local DOFs, i.e. when I try
+prog sofimsha
...
NODE NO 100 FIX -LMY
end
I get an error message complaining about an unknown character.
In SOFIMSHC however, I can specify local DOFs. However, there I can not use the same approach as with SOFIMSHA, i.e.
+prog sofimsha
...
SPT NO 100 FIX -LMY
end
Since there I get the error message saying node 100 is already defined.
Could someone please help me out here, thanks!
Best,
that doesn’t seam to work either. it says, unknown character
Hi,
Can you please send me your code so I can take a closer look? That way, it’ll be easier for me to help you correct it.

attached you’ll find my model.Benchmark - SHELL_model.dat (261.1 KB)
I just removed the “-” in front of LMY, and it worked fine.
But honestly, what’s the point of changing the support conditions by locking MY only at the end?
Abderrahman OMRI
The idea is to release the local MY DOF, hence the “-“ sign.
If I understood correctly, you want to modify the support conditions during the analysis. The best approach would be to define springs that represent your boundary conditions, and then activate or deactivate them in your calculation models using the groups assigned to them.
I believe this approach is more efficient!

This code works at my computer:

That works for me too, but that is globla coordinates and not local. I want to release local dofs
