 Even though Salome proposes some geometry simplification tools, from our point of view, these tools are not as efficient as the FreeCad ones. Even though Salome proposes some geometry simplification tools, from our point of view, these tools are not as efficient as the FreeCad ones.

-The geometry module allows you to import the step file and organize the geometry (in order to gain more control over the meshing process and the mesh refinements). You can then use the mesh module to effectively build the mesh. **We advise you to chose by default the NETGEN meshing algorithm**: it provides a nice compromise between robust mesh generation and ease of use.+The geometry module allows you to import the step file and organize the geometry (in order to gain more control over the meshing process and the mesh refinements).

 At this step, **it is also important to generate the groups of nodes and elements** that will be relevant later on when manipulating the SesamX model. For instance, you should prepare the groups for the [[user_manual:sesamx:functions_description:create_load|load]] and the [[user_manual:sesamx:functions_description:create_constraint|constraint]] cases definition. At this step, **it is also important to generate the groups of nodes and elements** that will be relevant later on when manipulating the SesamX model.
