I work with 3 subroutine: DLOAD - URDFIL and a code CFD
my code CFD which is transfer to 2 subroutine :
- (1) is pretreatment Data
- (2) is Main-loop

In Abaqus - There is an order that DLOAD -> URDFIL -> CFD code (Pretreatment -> Main loop)
But i got some trouble when i run abaqus: After finishing Pretreatment, the Main loop only run at the beginning of the subroutine - and close after that
but when a put pretreatment and main loop in a subroutine , it run normally.

Everybody has some ideas for my problem. Can share them ???
