ERROR: Too many attempts made for this increment - Wall and beam submitted to a distributed load

[Marquiavel]

Hey guys, I’m learning abaqus and now I’m trying to do an analysis of a wall submitted to a distributed load. This wall is in a contact with a beam. To represent the distributed load I use a uniform pressure, and to apply the boundary conditions in the beam I made two partitions representing the supports. When I try to do the analysis only on the beam I got any problems. However, when I add the wall this error occur: Too many attempts made for this increment.
Do you has any ideas about this problem? I using solid elements to represent both structures, is it a problem? Do you know what is the best element to represent a beam and a wall?
Thanks!
