Hi guys. I am analyzing a turbomachine with stator and rotor using CFX-11.0. I am using constant boundary conditions, corresponding certain operation point and obtain a steady state solution. I start my simulation with guessed stator and rotor blade angles. I am monitoring the efficiency of the machine while running the solution.

If the efficiency is not the one I am trying to reach, I stop the simulation and generate new meshes with different blade angles. I run the preprocessing again (import mesh+assign BCs etc.) and start simulation. By changing the angles of stator and rotor blades, I'll get appropriate efficiency eventually.

My question is that is it possible to import a new mesh in simulation while it is running? In other words, is it possible to replace old mesh with a new one while simulation in running? If that could be done I woudn't have to stop my simulation and run preprocessing each time I change blade angles.

In the iteration process that I described, BCs remain constant and the only thing that changes are stator and rotor blade angles. I am using a structural grid generator so the topology and sumber of elements remains the same for each mesh.

Thanks in advance
