HFSS: re-using the mesh of a solved design after changing a boundary impedance

I have a large model of an antenna and nearby structures that takes more than a day to solve. Part of the nearby structure includes a surface with a complex impedance. I need to make a copy of the model and change the impedance of this surface.
Right now, when I change the impedance value of the surface all solution data is invalidated and the entire analysis is re-run, including adaptive meshing passes. Since the model's geometry hasn't changed, I think the mesh from the last adaptive pass with the original boundary impedance will be good for my needs. Is it possible to re-use the mesh from the last adaptive pass of one model in another model that has an equivalent geometry? Or, is it possible to change the value of a surface impedance in a model without blowing away its mesh?

Nate T

indeed, as long as the physical geometry has not changed, HFSS can re-use the mesh. To do this, go to HFSS help and search "initial mesh import" and choose second option in HFSS14. You can even link the solved mesh from one project to another whereas you can change the boundary condition values.
