Automatic Solver Selection
|
The software selects the solver to run a topology study.
- The default solver with faster performance is the Intel Direct
Sparse.
- The FFEPlus (iterative) is the default solver only when
frequency constraints are defined.
- The Intel Network Sparse is not supported for Topology studies.

Run Static analysis before running topology
study
|
Selected by default. The software runs a static
analysis before running the topology optimization algorithm. |
Use inplane effect
|
Considers the effect of in-plane loading on the
calculation of the stiffness. |
Use soft spring to stabilize model
|
Adds soft springs attached to the ground to prevent
instability. If you apply loads to an unstable design, it can
translate and rotate as a rigid body. Apply adequate restraints to
prevent rigid body motion. |
Use inertia relief |
Applies inertial forces to counteract unbalanced
external loading. When selected, you can solve structural problems
without having to apply restraints or activate the soft spring
option to stabilize the model against rigid body motions. |
Use Min Max formulation (for load
cases) |
Select when multiple load cases can act on a component
independently (defined with the Load Case Manager). The optimization algorithm seeks to minimize the
compliance (reciprocal of stiffness) for each applied load
independently. The final shape of the component has the maximum
stiffness for the applied load cases that can act
independently.
