Hi everyone.

Im relatively new to OpenFOAM and am trying to investigate two phase non-Newtonian flow, for the purpose of simulating the injection moulding process using interFoam. Recently I created a new function object to calculate strain rate, with the intention of being able to demonstrate the effects of strain rate of different types of non-Newtonian fluids (based on injection polymers). I have now run into a problem however, in that when I run my function it is applied to the whole model and so the scale is thrown off due to the highest shear rates being found in the phase representing air, which I do not care about.

What i am wondering is if there is a way for me to apply this strain rate function to the polymer phase only, and not the air phase?

Thanks for any help that anyone may be able to give
