FMD: VOLUME MESHING COMPONENT 

This course will allow you to discover how to generate a 3D tetrahedral mesh using the transformation methods used to create new meshed models from an existing 2D or 3D mesh. You will learn to analyse the quality of the mesh obtained as well as view elements of the inner mesh.

FMS: SURFACE MESHING 

This course will allow you to discover how to create an FE model for a complex surface part, and how to simplify the geometric data to optimise the meshing process.

You will also learn how to manage the surface and beam meshes, modify meshes and nodes, and to control their interface and quality.
