External Decomposition#
External Decomposition = {yes | no}
Description / Usage#
This optional card controls whether to use the builtin METIS based decomposition in parallel or to use externally decomposed exodus files, such as through SEACAS decomp tool
- yes
Exodus files are already decomposed and will not automatically be decomposed
- no
This is the default when built with METIS, internal METIS decomposition will be used. Defaults to RCB when less than 8 processors and KWAY when 8 or more. See Decomposition Type to set preferred internal decomposition.
