General Constraints
Available with Adams Solver (C++) only
You can create a general constraint that defines an arbitrary constraint specific to a model. As its name implies, it is more general than the Idealized joints, which describe physically recognizable combination of constraints that are used to connect bodies together. You can also use the general constraint to equivalently define an existing idealized joint. Read more about the GCON statement in Adams Solver (C++) help.
We advise that you use the general constraint with caution. Be sure to read the Known Limitations in the GCON statement.
To create or modify a general constraint:
1. Do one of the following:
♦To create a general constraint, from the Joint palette or tool stack, select the General Constraint tool 
.
.♦To modify a general constraint, from the Edit menu, select Modify. From the Database Navigator that appears, select the general constraint to modify.
2. The Create/Modify General Constraint dialog box appears.
3. If you are creating a general constraint, in the Name text box, change the name for the constraint. Adams View assigns a default name to the constraint.
4. Enter a runtime function that Adams Solver (C++) forces to zero during the simulation. To enter a function expression, next to the f (q) = text box, select the More tool 
to display the Adams View Function Builder. For information on using the Function Builder, see the Function Builder online help. Learn more about defining a runtime function for a general constraint.

In the Report reaction forces on marker text box, enter a marker whose reaction forces are measured and reported as part of standard results. The reaction force reported is the force that is exerted on the marker to satisfy the constraint equation. Note that if you specify a marker and the runtime function has no dependency on it, the general constraint reports a zero force. The default is the ground coordinate system (GCS).
Note: | You cannot enter the Adams ID for the marker; you must enter the name of the marker. Learn about Adams Solver IDs. |
6. Select OK.
