From GAMBIT to TGRID
 

Hello everybody,

To construct a mesh 3D I construct a mesh in the faces using GAMBIT and then it is necessary to export this mesh to generate the mesh in the volume in TGRID. Nevertheless, when I try to do the mesh of the volume in TGRID an error throws me and he does not construct anything me.
What is the procedure step by step to construct a mesh 3d using these 2 programs?

Greetings
