For every load step, fortran code is complied from beginning, when we link with abaqus. My question is: if, for example, I am solving for a(t) and 't' is time at current load step and I want a(t) value in the next load increment a(t+1), how will I get value of a(t) ? Because for every load increment fortran code run from beginning and I don't know how to call/use, all previously solved/stored value. Can any one help?.
Hi rajkumar
Try to write the values you want to a file, and read it in the next step
Hope this helps
+1 for save. I/O operations (i.e. writing/reading to a file is extremely slow).
Since Abaqus control the computational process you can let it pass the required variable(s) as an argument to a Fortran subroutine, hence you will get it before and after the iteration.
my fotron code is called by abaqus for every load increment. i tried stored my output value by declaring another variable. But it is not working.
thanks to all.. my problem solved..thanks Hojjat Badnava, i followed the same. done.
