To whom it may concern;

I worked on a project and I am working on all simulations and calculations on Ansys. My aim in the Topology Optimization is not to remove unloaded regions, but my aim is to remove the regions that loaded acting forces and pressures coming from CFD and FEA, but unfortunately, I am not able to figure it out. I am kindly demanding your help.

Thanks in advance.

I am not sure I understand your question or your objective. 

Elements with forces and pressure loads applied to them are interpreted as being part of boundary conditions and are excluded from the Topology Optimization analysis by default.  This means that these elements will NOT be eligible for removal during the optimization run.  In general, this is usually a good thing as it prevents elements that are potentially part of the primary load path from being removed.  You can overide the default, but it might cause convergence trouble.  Kind of like kicking the legs out from under a table.
