1 material point failed to conrge

Hello ABAQUS Users,

I'm trying to run a simulation of a pushout test with steel deck in ABAQUS Explicit. I'm using CDP model for the concrete behavior. However, I'm facing a problem with it. I'm doing it for 50 MPa concrete but after some time some elements in the concrete exceeds the yield stress value and I get a warning message.

I've tried using Elastic Perfectly plastic model where I do not get such warning but while I switch to CDP I get this Everytime. Does anyone knows about this problem? Thank you!

Make sure that the load is not too high. You can try adjusting material properties and refining mesh.
