Parameter information
|
Variable Name |
Size |
Description |
|
time |
double |
Current simulation time of RecurDyn/Solver. |
|
upar |
double[30] |
Parameters defined by the user. The maximum size of array is 30. |
|
npar |
int |
Number of user parameters. |
|
jflag |
int |
When RecurDyn/Solver evaluates the Jacobian, the flag is true. Otherwise, the flag is false |
|
iflag |
int |
When RecurDyn/Solver makes its initial call to this routine, the flag is true. Otherwise, the flag is false. |
|
result |
double[3] |
Returned force vector and three-dimensional variables. |
