MeshExportCmgui2Cm
If you have built a mesh in cmgui interactively it can only be saved in the ex* format. In order to use the mesh in the backend it must be converted to ip* format and both the exnode and exelem files must be converted.
There are a number of perl modules that have been written for this purpose. These can be found in the cmiss_perl directory of your cmiss installation.
See CmUtils::Object::Node, CmUtils::Object::Element, CmUtils::Object::ElementGroup. The element conversion routines are in the ElementGroup module.
Update:
Cmgui now has a 'gfx export cm ...' command that can be used to export a mesh to .ip* format.
