SOLIDWORKS Simulation
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 Simulation Options > Default Options > Contact.
Stress Averaging at Mid-Side Nodes
The improved stress averaging algorithm applies to linear dynamic studies.
Before you run a linear dynamic study, in the Results Options PropertyManager, click
Average stresses at mid-nodes (high-quality solid mesh only).
For a high-quality solid element, the stresses at the mid-side nodes are calculated by
averaging the stress values at the adjacent corner nodes. This stress averaging method
improves the calculation of stresses at mid-side notes for tetrahedral elements with high
aspect ratios.
Example:
• Stresses at corner nodes (1, 2, 3, and 4) globally
averaged over the shared elements.
• Stresses at mid-side nodes (5, 6, 7, 8, 9, and 10)
averaged over the associated corner nodes. For
example, stress (node 5) = (stress (node 1) + stress
(node 2)) / 2
Thermal Loads for Beams
You can apply thermal loads on beam joints and beam bodies. After running thermal
analysis on a model with beams, you can import the temperatures into a Linear Static,
