interfacing a fluid solver with abaqus

Tuhin Rakshit

Hi

I am working on an FSI problem (flow past a circular cylinder). The tools I am using are the fluid solver Acusolve and the structural solver Abaqus. The fluid solver computes the forces on the body. Abaqus does the structural dynamics.

The issue - I have written a udf on the fluid solver side to compute the force on the body. I have written a user element on the Abaqus side for the structural dynamics. Now I have to create an interface between the two softwares, so that at each time step, the fluid solver passes the force values to Abaqus which does the structural part and feeds the motion of the body back to the fluid solver for the next time step.

Any ideas on this one? Please explain in as detail as possible.

Thanks tuhin
