Abaqus early termination in an inflation simulation with ALE
Abaqus early termination in an inflation simulation with ALE
(OP)
Hi all,
My Abaqus/explicit ALE simulation terminates before the target pressure load can be achieved. The geometry is consisting of 4 concentric circles, and one other circle which will be inflated with a pressure (DSLOAD). Due to this expansion, ALE is used to control mesh distortion. I have made the whole domain as the adaptive region. I have used very small incremental and performed mesh sweep at frequency=1. But the simulation still terminates early. I wonder whether you can check the attached inp file to see whether I have made mistakes or where I can make improvement.
I really appreciate your help!
Jay

I have already made the remeshing frequency of ALE to 1 with 10 sweeps. Do you think what may be wrong? It seems that you think I have some flaws that I am not aware of.

With these large deformations almost no material is linear which is the assumption of the material properties you are providing your model. Look into hyperelastic material properties like "Neo Hooke" I hope this helps.
