Parameter information
|
Variable Name |
Size |
Description |
|
time |
double |
Current simulation time of RecurDyn/Solver. |
|
upar |
double* |
Parameters defined by the user. There is no limit about the maximum size of array. |
|
npar |
int |
Number of user parameters. |
|
iflag |
int |
When RecurDyn/Solver makes its initial call to this routine, the flag is true. Otherwise, the flag is false. |
|
result |
double[8] |
Returned value and eight-dimensional variable. RecurDyn/Solver will report only six variables (result(2~4) and result(6~8)) of eight returned variables. |
