I have a problem with a subroutine ANEXP in MARC MENTAT 2013.1. I want to used it to model pchase change during cooling. I do not know exactly how it works.
Could someone please help me in that case and could briefly, shortly summarize
In my model I have attached in Material Properties the 'Thermal Expansion' with
the table-driven method, is that could influence something?
I do not know exactly when the subroutine is called. I have 125 elements in
model and 523increments. But when I write in soubroutine commend 'write to
file.txt' one parameter(for example temperature t(1) ) after only one increment
and 20 cycles I have something like 10 000 times this parameter written.
Does it mean the subroutine is called like 10 000 times?
Also, In examples I found the equation
eqexp(1) = coed(ndi)*tinc(1)
for thermal strain increment vector. Is this all what I need to provide for 3D model?
