DVMBRL2
Bulk Data Entry Relates a design variable to properties of MBD entities using a relationship defined by a DEQATN card. The equation inputs come from the referenced DESVAR values and the constants defined on the DTABLE card.

Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| ID | Relationship identity. ID
must be unique with respect to other DVMBRL1 and
DVMBRL2 cards. No default (Integer > 0) |
|
| TYPE | Property type to be
related. 1 No default (Character) |
|
| BID/EID | Body ID or Element ID
number. When TYPE is PRBODY,
this field is the ID number of a rigid body. When
TYPE is CMBUSH(M),
CMBEAM(M), or CMSPDP(m), this
field is the ID number of a corresponding element. No default (Integer > 0) |
|
| PNAME | Property name, such as "A"
or "L" (as in the documentation of the PRBODY,
CMBEAM(M), CMBUSH(M), and
CMSPDP(M) cards). No default (Character or Integer > 0) |
|
| EQID | Equation ID of
DEQATN data. No default (Integer > 0) |
|
| DESVAR | Indicates DESVAR ID numbers follow. | |
| DVIDi | DESVAR
ID. No default (Integer > 0) |
|
| DTABLE | Indicates DTABLE labels follow. | |
| LABLi | Constant label on
DTABLE card. No default (Character) |
