Hi there,
i want to model contact between 2 solid blocks but i get the following error:
ERROR ID : 612** ERROR IN INITIAL PENETRATION IN INTERFACE
How i can solve this error? I added the mode files.
Thank you very much for your help
Hi
for /INTER/TYPE7 the gap need to be defined. If you do not define the solver will set the Gapmin .
And in your case, it seems the parts are touching each other. For this scenario the initial penetration is found by solver.
The Inact flag can help on the initial penetration, but will not do that for your case as again the meshes are lying on each other.
For solid-solid interaction the TYPE7 need to have gap, even a small one will work. you can define that in the GApmin and have the parts apart by that gap value (translate one of the parts I meant)
Alternatively you may try to use /INTER/TYPE24 that for solid-solid does not require the definition of Gap value
I Hope this is helpful
Regards

thank you very much for your great explaination. Not found this info in the documentation. Now the simulation is running. I think i will get back when i encounter new problems
have a nice time
