I don’t know where is param.rho, except this, I think others are:

Thanks for the explanations, based on your discussion I was thinking you guys believe “force = 2*reduceImmersedForce(*container, iSurface)”, now it is clear and it seems the U_physical = 1 in your case.

I guess your code partially referred to the example generalExternalFlow.cpp, in that source code’s xml file it says the param.rho=1 and it is the density of fluid.

Yes, I referred to a lot of the code in generalExternalFlow. I meant that in my equation above, it doesn’t contain param.rho, so I don’t know why the final forceConversion has param.rho.
