Hi to all

I jumped into an issue in Abaqus Explicit and in particular in the very early increments (inflation of tire from standard to explicit).

At the initial increment I see that the RBFOR at the center of the ply is around 94.8 N and it’s correct because this value come from the import of the standard 3D (tire inflation). Below the attached viewport

the weird thing happen in the next increments.

Below there is exactly one increment later. I see that the RBFOR of PLY passed from 94.8 N to 54.8 N.

Could someone help me to understand the problem?

Thanks

Best
