*FIELD MAPPER CONTROLS

Define controls for the mapper.

This option can be used only in conjunction with the EXTERNAL FIELD option. It is used to define additional mapping controls for the field mapper when importing a predefined field to define a distribution or initial condition.

Required parameters

NAME

Set this parameter equal to a label that will be used to refer to the field mapper control definition. All field mapper control names in the same input file must be unique.

Optional parameters

CONFIGURATION

Set CONFIGURATION=DEFORMED to use the deformed configuration of the source mesh for mapping. This parameter setting is used when the model is remeshed in the second analysis using the deformed shape from the first analysis.

Set CONFIGURATION=REFERENCE (default) to use the original configuration of the source mesh for mapping.

TENSOR AVERAGING

This parameter is relevant only for mapping three-dimensional tensor quantities.

Set TENSOR AVERAGING=COMPONENT to use component-by-component mapping. This value is the default except if output variable S, ORIENT, or ORITENS is specified as the source field on the EXTERNAL FIELD option.

Set TENSOR AVERAGING=EIGENVALUE to use a mapping technique that preserves the eigenvalues of the tensor during mapping. This value is the default if output variable ORITENS is specified as the source field on the EXTERNAL FIELD option.

Set TENSOR AVERAGING=INVARIANT to use a mapping technique that preserves the Mises invariant of the stress tensor during mapping. This value is the default if output variable S is specified as the source field on the EXTERNAL FIELD option.

If output variable ORIENT is specified as the source field on the EXTERNAL FIELD option, a special averaging technique to map orientations is used by default. Output variable ORIENT is available in the output database (.sim) file if material orientation is defined in the element section definition.

Data lines to define mapping specifications

First line to specify searching tolerances

  1. The distance searched on the outward-normal side of a surface facet. The distance is relative to the characteristic element size. Specify a value between 0 and 1; the default value is 0.5.

  2. The distance searched on the inward-normal side of a surface facet. The distance is relative to the characteristic element size. Specify a value between 0 and 1; the default value is 0.5.

  3. The distance searched outside the source elements. The distance is relative to the characteristic element size. Specify a value between 0 and 1; the default value is 0.5.

Second line (optional, to be used to specify default values at orphan locations where search fails)

  1. Value assigned to the first component of the scalar, vector, or tensor field at orphan locations. Default value is 0.0.

  2. Value assigned to the second component of the vector or tensor field at orphan locations. Default value is 0.0.

  3. Value assigned to the third component of the vector or tensor field at orphan locations. Default value is 0.0.

  4. Value assigned to the fourth component of the tensor field at orphan locations. Default value is 0.0.

  5. Value assigned to the fifth component of the tensor field at orphan locations. Default value is 0.0.

  6. Value assigned to the sixth component of the tensor field at orphan locations. Default value is 0.0.

When the FIELD MAPPER CONTROLS option is referenced by the EXTERNAL FIELD option used in conjunction with the DISTRIBUTION option, the default values specified for the orphan locations overwrite the default values specified in the first data line of the DISTRIBUTION option. If the default values are not specified, the default values specified in the first data line of the DISTRIBUTION option are used. For tensor quantities, the default values are the components of the tensor in the global coordinate system.
