Update quadratic damping coefficients #5

Conversation

This PR changes the parameter name for the quadratic damping coefficients as a result of changes to the gz-sim7 hydrodynamics plugin made in gazebosim/gz-sim@fde6ec6. These changes are in releases gz-sim7_7.2.0 and gz-sim7_7.3.0.

Details

  • To retain the previous behaviour the second order stability derivative parameters (quadratic damping) require name changes: <xUabsU> becomes <xUabsU> etc.

See also:

- The hydrodynamics plugin changed the damping calculation in gazebosim/gz-sim@fde6ec6
- To keep the same behaviour the parameter names must change <xUU> becomes <xUabsU> etc.
