[Geoqus] On UTOL in SOIL TRANSIENT Analysis

[bsaad at po-box.mcgill.ca]

Good day dears
I am doing Consolidation nonlinear analysis (SOIL STEP. My analysis 
doesn't run unless I set up Max. Pore pressure change per increment to 
a high value (almost in the order of the applied load). I do not know 
if that affects the accuracy.. and how I can check that.?

ABAQUS Doc says in the example  :Wicking in a partially saturated 
porous medium, quote "UTOL, the pore pressure tolerance that controls 
the automatic incrementation, is set to a large value since we expect 
the nonlinearity of the material to restrict the size of the time 
increments during the transient stages of the analysis and we do not 
wish to impose any further control on the accuracy of the time 
integration"
Your comments about this issue, are greatly appreciated
