7. EM_MESH Namelist
The EM_MESH namelist specifies the mesh used by the induction heating solver. This is a 3D tetrahedral mesh imported from an ExodusII format disk file.
Note
- Required/Optional:
Required when electromagnetics is true.
- Single/Multiple Instances:
Single
7.1. Namelist Variables
mesh_file
Specifies the path to the ExodusII mesh file. If not an absolute path, it will be interpreted as a path relative the the Truchas input file directory.
- Type:
case-sensitive string
- Default:
none
coord_scale_factor
An optional factor by which to scale all mesh node coordinates.
- Type:
real
- Default:
1.0
- Valid Values:
> 0
rotation_angles
An optional list of 3 angles, given in degrees, specifying a counter-clockwise rotation about the x, y, and z-axes to apply to the mesh. The rotations are done sequentially in that order. A negative angle is a clockwise rotation, and a zero angle naturally implies no rotation.
- Type:
real 3-vector
- Default:
(0.0, 0.0, 0.0)
partitioner
The partitioning method used to generate the parallel decomposition of the mesh.
- Type:
case-insensitive string
- Default:
“metis”
- Valid Values:
“chaco”, “metis”, “file”, “block”
- Notes:
See the MESH namelist variable partitioner for a description of the options and their associated input variables. In particular, the METIS options listed there may also be specified in this namelist.
partition_file
Specifies the path to the mesh cell partition file, and is required when partitioner is “file”. If not an absolute path, it will be interpreted as a path relative to the Truchas input file directory.
- Type:
case-sensitive string
- Default:
none
- Note:
See the Notes for the MESH namelist variable partition_file
first_partition
Specifies the number given the first partition in the numbering convention used in the partition file. Either 0-based or 1-based numbering is allowed.
- Type:
integer
- Default:
0
- Valid Values:
0 or 1
