FSI and additional variable

Jorn

Hello, In ANSYS/CFX 11 I'm simulating flow as a result of solid deformation. The deformation repeats itself every second. I then want to simulate the behavior of an additional variable (say a dye in the fluid) for e.g. 30 sec. I now do this by recalculating the same mechanical deformation and fluid velocity every 'cycle' of 1 sec over and over again, the only difference is the additional variable. Is there a way to do this more efficient?

Thanks, Jorn
