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
