problem related to umat subroutine.
hi all,
i am working on abaqus and using umat subroutine.
after i wrote a simple example code(isotropic) on fortran language and make a model on abaqus, i tried to run it together. it is worked.
after, i changed the simple code to my own code(anisotropic code) and run it with abaqus. i
the result is following:
too many increment made for this increment.
for step 1 converge but not step2 step 3 step4.
I tried to reduce the time increment but not way even the mesh i changed.
the time step i used is dynamic implcit
I wonder if someone can give advice or idea how to solve this problem? becoz i am really need a help as soon as possible. Merci
thanks you
best regards,

max increment number
Abaqus Standard has by default an upper limit of 100 increments per step.
Set the parameter INC to the command STEP.
