Argument |
Options |
Description |
||
SID |
<INTEGER> |
setid |
The 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 |
(Optional) 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 |
(Optional) 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 7th entry, the RIGID element IDs must be unique. |
|
|
||||
CONVOL |
<INTEGER> Default = blank |
cysid |
(Optional) The GRID set consists of Grids used to define the control volume. |
|
Comments
| 1. | There can be multiple PFPATH cards with the same SID. However, the connection points should be the same across all the PFPATH entries. |
| 2. | 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. |
| 3. | 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. |
