Argument	Options	Description
`SID`	<INTEGER>	setid `SID` is referenced by a PFPATH card in the control section.
`CONPT`	<INTEGER> No default	gsid The connection points with a `SID` of type GRID SET.
`RID`	<INTEGER> No default	rsid The response `SID` of type GRIDC. Contribution to each response DOF through the connection points will be calculated.
`RPTYPE`	DISP/VELO/ACCE Default = DISP	Criterion for the type of the response; the response type corresponding to a structural degree of freedom could be displacement, velocity or acceleration.
`CONEL`	<INTEGER> Default = blank	esid The ELEMENT set consists of elements connected to the connection GRIDs in `CONPT`. These elements represent connecting paths from the rest of the system to the user-defined control volume.
`CONREL`	<INTEGER> Default = blank	rsid The RIGID set consists of the RIGID elements, connected to the connection GRIDs in `CONPT`. These rigid elements represent connecting paths from the rest of the system to the user-defined control volume. If `CONREL` is specified in the 7^th entry, the RIGID element IDs must be unique.
`CONVOL`	<INTEGER> Default = blank	cysid The GRID set consists of Grids used to define the control volume.

There can be multiple PFPATH cards with the same SID. However, the connection points should be the same across all the PFPATH entries.
If CONEL and/or CONREL are specified, the set should consist of all the elements outside the control volume connected to the connection GRID's in CONPT.
If CONVOL is not specified, OptiStruct will export a file called, <filename>_outsidecv.fem, which contains a list of all GRID's outside the control volume. This file can be imported into HyperMesh to visualize the grids outside the control volume.
