- filenameThe name of the file containing the EBSD data
C++ Type:FileName
Controllable:No
Description:The name of the file containing the EBSD data
EBSDMeshGenerator
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 EBSDMeshGenerator 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.
Input Parameters
- num_cores_for_partitionNumber of cores for partitioning the graph (dafaults to the number of MPI ranks)
C++ Type:unsigned int
Controllable:No
Description:Number of cores for partitioning the graph (dafaults to the number of MPI ranks)
- pre_refine0Number of coarsening levels available in adaptive mesh refinement. The resulting mesh will have one mesh element per EBSD data cell, but will be based on a refined coarser mesh with 'pre_refine' levels of refinement. This requires all dimension of the EBSD data to be divisible by 2^pre_refine.(this parameter was formerly called 'uniform_refine')
Default:0
C++ Type:unsigned int
Controllable:No
Description:Number of coarsening levels available in adaptive mesh refinement. The resulting mesh will have one mesh element per EBSD data cell, but will be based on a refined coarser mesh with 'pre_refine' levels of refinement. This requires all dimension of the EBSD data to be divisible by 2^pre_refine.(this parameter was formerly called 'uniform_refine')
- show_infoFalseWhether or not to show mesh info after generating the mesh (bounding box, element types, sidesets, nodesets, subdomains, etc)
Default:False
C++ Type:bool
Controllable:No
Description:Whether or not to show mesh info after generating the mesh (bounding box, element types, sidesets, nodesets, subdomains, etc)
Optional Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:No
Description:Set the enabled status of the MooseObject.
