user_Derivative module

Module for the definition of the derivatives of the user states.

Summary

The user derivatives allows to add some equations to be time-integrated with the multibody system.

user_Derivative.user_derivatives(mbs_data)

Compute the derivatives of the user states.

Parameters

mbs_data (MBsysPy.MbsData) – The instance containing the multibody project. The derivatives values must be filled in the ‘uxd’ attribute which is a numpy.ndarray. The first index (mbs_data.uxd[0]) must not be modified. The first index to be filled is mbs_data.uxd[1].

Returns

Return type

None
