[[EM.Cube]]'s computational modules use a number of different mesh generation schemes to discretize your physical structure. Even CubeCAD provides several tools for object discretization. In general, all of [[EM.Cube]]'s mesh generation schemes can be grouped into three categories representing their dimensionality:
# Linear Mesh# Surface Mesh# Volume Mesh
The linear mesh is , also known as the wireframe mesh and , is used by [[EM.Libera]] to discretize the physical structure for Wire MoM simulation. [[EM.Cube]] offer two surface mesh types: triangular surface mesh and hybrid surface mesh. As its name implies, a triangular surface mesh is made up of interconnected triangular cells. [[EM.Terrano]], [[EM.Illumina]], [[EM.Libera]] and [[EM.Picasso]] all use triangular surface mesh generators to discretized surface CAD objects and the surface of solid CAD objects. The hybrid surface mesh is [[EM.Picasso]]'s default mesh. It combines rectangular and triangular cells to discretize planar structures. The hybrid surface mesh generator tries to produce as many identical rectangular cells as possible in rectangular regions of your planar structure.
[[EM.Cube]] provides two types of brick meshes to discretize the volume of your computational domain. Brick meshes are entire-domain volume meshes and are made up of cubic cells. Brick meshes are indeed generated by a three-dimensional arrangement of grid lines along the X, Y and Z dimensions. [[EM.Tempo]] offers an Adaptive brick mesh as well as a fixed-cell brick mesh for the FDTD simulation of your physical structure. [[EM.Ferma]] offers only a fixed-mesh brick mesh for the solution of electrostatic and magnetostatic Poisson equations.
