!PARTITION¶

Line 1¶

!PARTITION, TYPE=<type>, METHOD=<method>, DOMAIN=<domain> [, optional parameter]

Parameter	Description
TYPE	Domain decomposition type (required)
METHOD	Domain decomposition method (required)
DOMAIN	Number of domains (required)
DEPTH	Overlap depth (optional)
UCD	Output of a UCD file for visualizing the domain decomposition (optional)
CONTACT	Handling of contact nodes in domain decomposition (optional)

Parameter	Parameter value	Description
TYPE	NODE-BASED	Node-based decomposition
	ELEMENT-BASED	Element-based decomposition
METHOD	RCB	RCB method; the decomposition reference axes must be specified on line 2
	KMETIS	kMETIS
	PMETIS	pMETIS
DOMAIN		Number of domains
DEPTH		Overlap depth of subdomains (DEPTH=1 if omitted) Cannot be specified when TYPE=ELEMENT-BASED
UCD		UCD file name (optional)
CONTACT	DEFAULT	Perform ordinary domain decomposition without considering contact nodes (handled the same as SIMPLE)
	AGGREGATE	Assign the master and slave surfaces to the same subdomain
	DISTRIBUTE	Distribute the nodes on the master surface evenly among the subdomains
	SIMPLE	Perform ordinary domain decomposition without considering contact nodes (handled the same as DEFAULT)

(Line 2) DIR1, DIR2, DIR3, ... (specify for the number of decompositions)

Variable name	Attribute	Description
DIRX	C	Decomposition reference axis (specified using lowercase x, y, or z)
