Hello,
I have an issue with Abaqus snap thru phenomena. The calculations are not stable so I can not converge the model, or the model is converged after may iterations or the convergence criteria (25mm) is not reached. I think I need some control parameter to path the calcualtions in a right way.
Could you help me? What and where should I add. Thank you in advance.
here is the main part of the input.
*BOUNDARY
NSET_FIX,1,6,
*INITIAL CONDITIONS, TYPE = TEMPERATURE
ALLNODES,90
*STEP, INC = 1000, NAME = snap_thru, NLGEOM = YES
*STATIC, RIKS
,,,,, 506118, 1,-25.00
*DSLOAD
surf_pressure_load,P,0.0001
*OUTPUT, FIELD
*NODE OUTPUT
U
*ELEMENT OUTPUT
S,PEEQ
*END STEP
