In virtual Wind Tunnel VWT 13.0 the information from the run dialog (meshing, setup) is saved into the *.stmod file. So you can use that file as a template to study different designs.
To make sure, that all design variations (e.g. generated by morphing) are at the same position, I recommend to move the wind tunnel during the positioning process instead of the body. Delete the body and save that file as *.stmod. Now you have a template.
