Parallel coding of Abaqus subroutines

[compositessolution]

Hi, I am using Abaqus vuel and vumat subroutines. It seemed that the Abaqus explicit solver is much slower than LS-Dyna explicit, I wonder if this is true or I didnot set the time step control in Abaqus correctly?

To speed up the simulation, I want put some parallel coding in the Abaqus subroutines. In LS-Dyna coding, I simply need to include 'mpif.h' below the subroutines, then I can use the MPI functions such as MPI_ALLREDUCE, but in Abaqus, " include 'mpif.h' " didnot work. Does anyone have the experience of parallel coding in Abaqus subroutines? Can you give me any clue of this?

Thanks a lot.

Abaqus subroutines work in parallel by default, as long as your are careful with the use of common blocks etc. As far as I know there is no functionality to allow the direct use of MPI functions however.

Thanks a lot, MechIrl. I need to use lots of common blocks in the Abaqus subroutines. I will try to see if I can replace common blocks with other variables now.
