Subject: Re: Abaqus post-rpocessing issue
Hi
The subroutine UVARM can be used to define a user defined post-
processing variable, however I do not have a fortran compiler on my
m/c.
For the product of strain and strain rate, why not create a field
varaiable in abaqus cae defined as:
E*ER (small strains)
LE*ER (large strains)
For example, to create a field variable for step 1 increment 7 the
expression should be of the form:
s1f7_LE*s1f7_ER
The tensor multiplication is recognised automatically. My problem
concerned incorporating user defined data which is a function of a
field variable.
Regards
Barry
