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. |
|
iord |
int |
Integrator order. |
|
iflag |
int |
When RecurDyn/Solver makes its initial call to this routine, the flag is true. Otherwise, the flag is false. |
|
result |
double |
Returned value and one-dimensional variable. |

Figure 1 Example Model using Motion User Subroutine
Note
If the user wants to run this model using a user subroutine, the user can refer it in the directory (<install dir>/Help/usub/**).
Motion User Subroutine can only be used as displacement.
