MORPH_AREA

Using the MORPH command, the single morphing areas (MORPH_AREA), the morphing parameter file and the optimization task are combined: 

MORPH
  ID_NAME  = <morph_name>   [string]
  OPTIMIZE   = <optimization_name> [string]
  MORPH_AREA  = <MORPH_AREA_name_1>   [string]
  MORPH_AREA  = <MORPH_AREA_name_2>   [string]
  MORPH_AREA   = …
  MORPH_PARAM_FILE  = <morph_csv_file_name> [string]
  NUMBER_OF_PARALLEL_JOBS = <number>
  SMOOTHING = YES|NO [string]
  MASTER = AUTO | MIN | MAX | MINABS | MAXABS | SUM | CSV
END_

The parameter NUMBER_OF_PARALLEL_JOBS defines optionally a number of jobs which can be run in parallel. If omitted or =1, a sequential run will be performed (default).

SMOOTHING is another optional parameter that switches off the surface mesh smoothing for the nodes in the morph areas. By default surface smoothing is omitted to gain the exact displacement as specified in the csv-file. However some manufacturing constraint might not work as expected in this case.

The MASTER criteria is a great help to gain control about the order in which the morph areas are processed. This is especially important if you work with overlapping morph areas.

  • AUTO: (Default, same behavior as in previous versions) Order as specified as in the csv file, but morph areas with zero displacement are processed last and thus being most important.
  • MIN: Morph areas with the smallest displacement specified in the csv file are processed last.
  • MINABS: Morph areas with the smallest absolute displacement (e.g. 0) are processed last.
  • MAX: Morph areas with the greatest displacement are processed last.
  • MAXABS: Morph areas with the greatest absolute displacement are processed last.
  • SUM: If nodes are referenced in multiple morph areas, the displacements are summed up.
  • CSV: Order exactly as specified as in the csv file.
