Cartesian

Menu: Mesh->Cartesian

A cartesian mesh is a mesh where all elements are bricks with equal size, and edges parallel to the XYZ cartesian axes.

The grid nodes can be referenced with integer index i,j,k

This kind of grids are useful for Finite Differences methods.

example: from lef to right the original geometry and two cartesian meshes

It's possible to set this kind of meshing to any geometric entity: volumes, surfaces, lines and points.

e.g, for a line entity the cutted voxels will be obtained as hexahedral elements.

The voxel size is set by the general mesh size (equal for X, Y and Z directions)

At this moment boundary conditions are not transfered over this kind of meshes
