Dear colleagues

I have written a user element subroutine by FORTRAN but when I call it through the ABAQUS (version 6.4), during loading the inp file, an error produces related to FORTRAN compiler (Compaq visual Fortran 6.5) as below:

ABAQUS JOB 2

ABAQUS version 6.4-PR11

Hello to everybody

I want to detect strain localization in geological materials and follow the path and the way that shear band propagate in seismic condition, so I want to know is there any meshfree commercial package to handle dynamic nonlinear analysis for geological materials specially rock and soil. Does exist Even a good source code that i improve it (not so much) and make it effecient for my purpose ?

I appreciate anyone help me and give me information in such field.

Truly

Babak
