Error during analysis of job

[technodam]

hello,
I am doing the simple analysis of bracket with 2 horizontal holes. i applied pressure on the top of the bracket and fixed the bottom of the plate in X-direction.
can anyone tell me, What does the error ‘Too many attempts made for this increment’ mean? and what would be the possible reason for this and what would be the solution?

Too many increments means exactly what it says, the Newton-Rhapson method can not converge in the number of increments that are specified (5 times cutback in increment time).

If you are doing a simple analysis there are either more warnings (numerical singularities and/or negative eigenvalues) which suggest you didn't define your BC's well, or you are taking a too large initial time increment, but if you are doing a simple linear elastic test even a time increment of 1 should be enough, so it's probably a matter of boundary conditions.
Or an extremely bad mesh.

The warning shown is
'2208 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.

No output variables associated with this field output group.'

so what would be the cause of this warning? I havn't got it.

Or you are loading unrealistically high/fast
Or you messed up units in loading, material stiffness and dimensions.
