abaqus - solving penetration contact error between 2 surfaces

abaqus - solving penetration contact error between 2 surfaces

abaqus - solving penetration contact error between 2 surfaces

(OP)
I'm finding that I have the following message:

MAX. PENETRATION ERROR 11.0035E-03 AT NODE PIPELINE-1.638 OF CONTACT PAIR
(ASSEMBLY_PIPELINE,ASSEMBLY_CLAMPTOPINSURF)
MAX. CONTACT FORCE ERROR 1.48954E-03 AT NODE PIPELINE-1.645 OF CONTACT PAIR
(ASSEMBLY_PIPELINE,ASSEMBLY_CLAMPTOPINSURF)
PENETRATION ERROR TOO LARGE COMPARED TO DISPLACEMENT INCREMENT.


To solve I've tried the following:

- lowering increments in Step to 1e-5
- I tried offsetting the one surface from the other (to try and stop penetration error?!)
- changing the interaction properties definition from hard contact to linear contact, with stiffness 10,000 and set NLGEOM on.

I'm running out of ideas... any pointer's??

The model I'm current working on is Model-1_31Aug in the cae file uploaded....

Thanks

RE: abaqus - solving penetration contact error between 2 surfaces

This would be better posted in forum799: ABAQUS: ABAQUS FEA Solver where everyone uses Abaqus rather than here, where many people do not. If you do decide to post over there, as is strongly recommended, please delete this post by using the "Inappropriate post? If so, Reg Flag it!" option in the bottom middle of the thread and letting the system administrator know that you have posted in a more appropriate forum. Thank you.
