Convergence Issue while performing abaqus explicit followed by standard

[Ali asger]

Hi there, I am working on composite slab subjected to impact load in abaqus, i have modelled slab in abaqus explicit and applied impact by giving velocity to a rigid body andd now i want to find reduced capacity of slab by performing four-point bending test, so i had used predefined field to import deformed state of model in abaqus standard but the model is not converging in its 1st step itself it is showing zero pivot problem in waring

any idea how to solve convergence issue?

Thankyou

How is the model constrained in the second analysis (the one using import) ?
