A static analysis is performed to simulate extrusion under fluid-penetrating pressure loading.

Because the deformation is large and complex, large-deformation effects are enabled (NLGEOM,ON).

The following analysis options are used:

nlgeom,on
nsubst,100,10000,100
outres,all,all
cutcontrol,plslimit,1
cutcontrol,noiterpredict,1
pred,off
lnsrch,on
nropt,unsym

The allowed limit for equivalent plastic strain is increased due to expected large plastic deformation of the elements.

The line search option in the Newton-Raphson solver and the full Newton-Raphson option with unsymmetric matrices are used.
