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


Exodus files are already decomposed and will not automatically be decomposed


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.


Following is a sample card:
