Using Contact with CalculiX 1.6?
Using Contact with CalculiX 1.6?
(OP)
I am unable to get some really simple contact models in Calculix 1.6 to converge. Has anyone had success with this new feature? It looks very promising. I can paste my simple input deck if you want to give it a try.

I am tryng to run a simpler version of the contac2.inp model that is in the test folder. I converted the elments to C3D8 and just defined contact on the last two elements of the beams.
However the model is unable to converge. Here is the relevant portion of my input deck:
*SURFACE,NAME=Smast
58, S6
60, S6
62, S6
64, S6
*SURFACE,NAME=Sslav,TYPE=NODE
203,205,222
*CONTACT PAIR,INTERACTION=SI1
Sslav,Smast
*SURFACE INTERACTION,NAME=SI1
*SURFACE BEHAVIOR
4.6e-3,4.
*STEP,NLGEOM,INC=100
*STATIC
*BOUNDARY
Nfix,1,3
*CLOAD
496,2,250
*NODE FILE
U
*EL FILE
