4.35. Compare Mesh

The mapping quality is questioned more frequently as more people use the mapping algorithms and its expanding options for mapping, data transfer and more. As a result, the Envyo application now holds an experimental return mapping algorithm which is adjusted based on customer needs. The main idea is that a simple closest point mapping is performed between the source and target mesh, and once the data is transferred from the source to the target, then the source value is subtracted from the target value (target side value - source side value). The result is stored on either the integration point or node. Use the result file to fringe the different values and see the difference between the two meshes.

Only stress, strain, and thickness values are transferrable. This also includes history variables.

4.35.1. Main Mapping Command

ENVYO = COMPARE MESH

4.35.2. Additional Input Information

SourceFile = STRINGDefine the name and, if needed, the path of the source file.
TargetFile = STRINGDefine the name and, if needed, the path of the target file.
SourceFileFormat = LS−DYNAEnables specifying the source file format. Only LS-DYNA is supported.
MappingResult = STRINGDefine the result file name. The mapping result is written into this newly generated file.
ALGORITHM = ClosestPointThe ClosestPoint option accounts for most of the mapping purposes being targeted with the Envyo application. Beginning from the target mesh, the next element or integration point is identified, and its data is transferred onto the target mesh.
SORT = BUCKETAlways use bucket sort for a significant speed up of the search algorithm.
REPEAT = YESEnable this option to ensure that all elements and integration points receive mapped data. When there is a significant difference in element sizes between the source and target meshes, the default bucket refinement may be insufficient to cover all points, sometimes by design. In such cases, this flag must be set to guarantee complete data coverage.

MapStress = YES

NO

Activates or deactivates stress mapping for mesh comparison.

MapStrain = YES

NO

Activates or deactivates strain mapping for mesh comparison.

MapThickness = YES

NO

Activates or deactivates thickness mapping for mesh comparison.
