📝 Description
Current situation:
The current implementation of
StructuralMechanicsBossakSchemedoes not update the angular time derivativesANGULAR_VELOCITYandANGULAR_ACCELERATION.This PR adapts the
StructuralMechanicsBossakSchemeto allow transient simulations of structures containing elements with rotational dofs. Therefore the methodsPredict,UpdateandInitializeSolutionStepare extended. The extended implementations are analogous to those of the base methods in theResidualBasedBossakDisplacementScheme, whereby the corresponding degrees of freedom are replaced by their angular counterparts.🆕 Changelog
