/fixes
elementary_server, solver_Z_impedance
- Wrong sign of the elementary gyroscopic damping matrices (beam and disk, following spin axis)
solver_modal
- Convergence issues fixed (in cases of bad conditioning).
solver_modal, solver_buckling_Euler
- Could crash.
solver_modal, solver_modal_gyroscopic, solver_mass, elementary_server
- Crash with line mass models and hard offsets and
FEM_LUMPED_MATRIX
.
solver_static_Newton
- Fixed convergence issues with prescribed displacements and non-linear
user_stiffness
(with call-back).
/breaking changes
solver_Z_impedance
- Initial solution
data_type::initial
is no longer considered as periodic.
It’s used only now in the computation of the tangent stiffness matrix with non-linear models. - Dirichlet conditions (prescribed values), thermal loads and pre-strains are no longer not considered in
RHS
.
