EBSDMesh

Mesh generated from a specified DREAM.3D EBSD data file.

The mesh is generated from the EBSD information, to get an optimal reconstruction of the data. This is accomplished in the mesh block using the EBSDMesh type. The same data file used with the EBSD reader is used in the EBSDReader UserObject. The mesh is created with one node per data point in the EBSD data file. If you wish to use mesh adaptivity and allow the mesh to get coarser during the simulation, the "uniform_refine" parameter is used to set how many times the mesh can be coarsened. For this to work the number of elements along _each_ dimension has to be divisible by where is the value of the uniform_refine parameter.

warningwarning:"uniform_refine" parameter

Contrary to other mesh objects the "uniform_refine" parameter will not affect the resolution of the final mesh. It sets the levels of coarsening that can be applied to the EBSD data.
