| models.muscle.System.UseCrossFibreStiffness |
Flag to indicate if this system should use stiffness terms (Markert) for cross-fibre directions.
Default: false
Dependent set to true. | models.muscle.System.UseDirectMassInversion |
Flag to invert the velocity mass matrix before simulations.
If this is set to true, the mass matrix for the velocity part will be assembled, the boundary condition rows removed and the inverse of the remaining matrix will be pre-computed. This inverse will be pre-multiplied to the velocity-dofs inside the models.muscle.Dynamics evaluate and getStateJacobian functions.
This in general results in higher simulation speed but it remains open to see how well reduced modeling will work with that scheme.
