Underconstraint model

Underconstraint model

(OP)
Hello there.

I have underconstranted model, and error that occur is 9137(PHADE1D, but thats another problem. What i am interested is, when that error occur, and we get the GRID POINT SINGULARITY TABLE in F06 file, is there listed all nodes of model or node listed are just the ones that are underconstraint (have excessive pivot rations)?
I get all nodes listed, with failed directions 4,5,6 (i assume that is rotational DOF). I am using Femap

Thanks in advance!

Grozozo.

RE: Underconstraint model

Can you post some pictures of load applied, BC's applied? Its difficult to suggest something without seeing the model. Try constraining the rotational DOF's at one of the nodes. You need min DOF's constrained to achieve equilibrium.

Alternately regarding your error, you can search in the forum1234: Siemens: Femap.
