changing values of boundary condition during running simualtion

I use SolidWorks Flow Simulation. I want to change the flow
rate values of a boundary condition by the API during a running CFD simulation.
After an iteration measurements are read by the API. Then, an external program calculates
new boundary conditions that are passed to the API (Co-Simulation).


Currently I stop the simulation after one interationstep by
the API, then I change the values of the boundary conditions (by the API) and start
the simulation for the next iterationstep (by the API). But the start and stop
takes far too long time. Sometimes the CFD solver hangs in the point
"model is being prepared".


Is there another way to change the values of boundary
conditions during a running simulation, without stopping the Solver?


I would appreciate very much if you would answer me.
