Performance improvements are implemented for linear static studies with
multiple load cases and studies with contacts set to incompatible bonding.
Linear Static Studies with Multiple Load Cases
You see performance benefits while solving a simulation for linear static
studies with multiple load cases defined with remote loads. The force and moment
components of remote loads support the optimized solver performance. Translation,
rotation, and mass components of remote loads remain unchanged for all load
cases.
Performance is not improved when no-penetration contact or virtual
wall contact are present in any load case.
The Intel Direct Sparse solver performs the global stiffness matrix
factorization (which consumes the majority of the total solution time) only once,
because the stiffness matrix remains the same for each load case.
The optimized reconfiguration of the Intel Direct Sparse solver
was introduced in SOLIDWORKS Simulation 2019, and it was realized for pressure,
force, and torque load types.
Incompatible Bonding
The algorithm of the surface-to-surface incompatible bonding is
improved. The solver calculates correctly the zero-stress state and zero frequencies
for rigid body modes.
The calculation of stresses at bonded interfaces with unmatched
(incompatible) meshes is also improved.
The default option for bonded component contact is now set to Incompatible mesh. You can change the mesh setting
for the Component contact (including the Global
Contact option) to Compatible
mesh or Incompatible mesh for
a bonded contact type from .
