Items

Gravity: You can set the gravitational acceleration to any desired value.
Hard Coded: choose this option if you want to optimize for speed.
As Parameter: Use a gravity parameter, allowing you to change the value before the start of a simulation run.
As Input Signal: get the gravity value from an input signal, allowing you to change the value during simulation.
Spring Dampers for Constraint Joints: Choose this option if you want to use spring dampers for closed kinematic chains. You can override the spring damper values for individual joints if required.
Rotation Spring: Set the desired stiffness for the rotational spring.
Rotation Damper: Set the desired rotational damping.
Rotation Spring: Set the desired stiffness for the translation spring.
Translation Damper: Set the desired translation damping.
Reference Frames: Choose the size and thickness of the reference frames.
Grid: Set the grid.
Angle Representation: 20-sim uses SI-units for the model equations (e.g. radians). You can choose to show them in non-SI-units like degrees or grads.
Power Port Type: Choose Iconic Diagram power ports or bond Graph power ports.
Constraint Solver: set the accuracy of the constraint solver.
