Calling sequence : CALL DITOP (IDENUM, ITYPE, IGROUP, MAT, NODES, IDSNUM, IEXIT, IUNT)
Purpose : To enter element topology.
Parameters :
| In | |||
| IDENUM | Element identification number (Integer) | ||
| ITYPE | FEMVIEW element type (Integer) | ||
| IGROUP | Group number (Integer) | ||
| MAT | Material number (Integer) | ||
| NODES | Node numbers (Integer array of length 20) | ||
| IDSNUM | Local Axis system number (Integer) (Not currently used) | ||
| IUNT | Temporary file channel number (Integer) | ||
| Out | |||
| IEXIT | Error condition | ||
Use : This routine is called once for every element in the model. Only element types as defined in the Appendices to the FEMGV User Manual may be used. Point elements (ITYPE=20) are allowed but discarded by this routine. Any re-ordering of the nodes has to be performed before calling DITOP.
Elements may be entered in any order, but note that element results must be entered in the same order as is defined when entering element topology.
Errors : The error condition is indicated by the value of IEXIT.
| IEXIT | Meaning |
| 0 | Successful call | |
| 32 | Current error must be cleared up first | |
| 132 | Cannot enter element topology, current dataset is : (KEY) | |
| 211 | Invalid temporary file unit number (iunt) | |
| 213 | Node identification numbers cannot be less than 1 | |
| 216 | Error in writing to temporary file on unit (iunt) | |
| 217 | Element id numbers cannot be less than 1 | |
| 218 | Invalid element type number (itype) | |
| 221 | Element id above 99999 not allowed for 5 digit character file | |
| 253 | System id numbers cannot be less than 0 | |
| 254 | System id numbers above 999999 invalid | |
| 255 | System id above 99999 invalid for character file |
