KEY, MPCID, TYPE, NSLAVE, NMASTER
To be written with the format:
FORMAT(1X, I2, 4I5)
Where:
| KEY | = | -1 for a data header record |
| = | -3 for the data set delimiter record which is an | |
| otherwise blank record inserted at the end of the data set. | ||
| MPCID | = | MPC identifier |
| TYPE | = | MPC type code |
| 1 | = | rigid connection of freedoms 1 through 6 |
| between one slave and one master node (RBEAM) | ||
| 2 | = | rigid connection of a single freedom from 1 to 3 |
| between one slave and one master node (RROD) | ||
| 3 | = | rigid connection of a single freedom from 1 to 3 |
| between one slave and one master node (RRODS) | ||
| 4 | = | connection of freedoms of two co-incident nodes (CONNECT) |
| 5 | = | connection of freedoms of two co-incident nodes (CQUAB) |
| 6 | = | keeping the slave in a fixed relative position |
| on a line defined by master nodes (CLINE) | ||
| 7 | = | keeping the slave in a fixed relative position |
| on a surface defined by master nodes (CSURF) | ||
| 8 | = | connection of shear freedoms of a slave to shear |
| freedoms of master nodes (CSHEAR) | ||
| 9 | = | a hinge connection between a slave and a master node. |
| An additional node is used to define the hinge axis (HINGE) | ||
| 10 | = | a slave connected to the edge of a surface defined |
| by two master nodes and one additional node (CLINE2H) | ||
| 11 | = | a slave connected to a master node in the direction |
| normal to a surface defined by one master and two | ||
| additional nodes (CSURF3N) | ||
| 12 | = | rigid body motion (RBODY) |
| 13 | = | weighted rigid body motion (RBODYW) |
| 14 | = | Direct set up MPCs |
| NSLAVE | = | number of slave nodes |
| NMASTER | = | number of master and additional nodes |
Then for TYPEs 1 to 11, followed by a single data continuation record specifying the slave/master connections. Note that master nodes should be specified before any additional nodes. Of the form:
KEY, SLAVE, IDOF, COEFF, MASTER1, ........ MASTERn
To be written with the format:
FORMAT(1X, I2, 2I5, E12.5, 9I5)
or: FORMAT (1X, I2, I10, I5, E12.5, 9I10) for 10 digit node number format
Or for TYPEs 12 to 14, followed by a separate data continuation record for each NSLAVE and then each NMASTER node of the form:
KEY, NODE, IDOF, COEFF
To be written with the format:
FORMAT(1X, I2, 2I5, E12.5)
or: FORMAT (1X, I2, I10, I5, E12.5) for 10 digit node number format
Where:
| KEY | = | -2 for a data continuation record. |
| SLAVE | = | node number of slave node. |
| IDOF | = | freedom numbers connected to the master node(s) |
| 1 = x-translation | ||
| 2 = y-translation | ||
| 3 = z-translation | ||
| 4 = x-rotation | ||
| 5 = y-rotation | ||
| 6 = z-rotation | ||
| 9 = all | ||
| Any integer which is a combination of at most five of the digits | ||
| 1-6 is a valid freedom. | ||
| COEFF | = | weighting coefficient |
| MASTER1 | = | node number of 1st master node. |
| MASTERn | = | node number of nth master or additional node. |
| NODE | = | node number of master, additional reference or slave node. |
