9 A main feature of HEXABLOCK is to define a geometry without constraint for hexahedral meshing.
11 The user has two ways to define the geometry for meshing:
13 - import a geometry from a STEP, IGES or BREP file,
15 - build a geometry with GEOM component.
17 The following pictures show different geometries for exemples:
