DVMBREL2 – Relates Design Variables to Properties of MBD Entities via Relationship Defined by User-supplied Equation
Description
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.

Field |
Contents |
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 (see table below). 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) |
