Problem with ABAQUS

[CapEng]

Hi everyone,

I'm a fresh user, and I'm getting mad with my last simulation of a hydroforming processes. I'll try to explain in the best way possible: I have modelled a matrix (as a rigid body), I hava an aluminium sheet, and I set the pressure thansk to which the sheet has to be deformed. The problem stands in the output data analysis: I tried to portrait both the maximum and the minimum in plane deformation (in the visualization area) using the XY data. I exported all the data on an excel sheet and I found that the deformation has a strange behaviour: the deformation varies a lot with respect of time, and this causes me lots of trouble in interpreting the value of the deformation at different time instants.
This problem can be solved acting on some of the option of the step defined? Or among the job options?
I hope I've been clear, and I hope you'll help me in solving my problem.
Thanks a lot

Antonio

First this is probably better posted on teh Abaqus forum:

Second, including pictures and simplified models greatly improves the help you will receive.

Thank you.
