Selecting the Physics Models

Select physics models to set up a static linear analysis.

The physics models define the primary variables of the simulation and which mathematical formulation is used to generate the solution. In this simulation, the structure displacement and the internal stress distribution are computed using the Sparse Direct Solver, which is activated when you select the Solid Stress model.
  1. Create a physics continuum and rename it to Plate Physics.
  2. For the physics continuum, Plate Physics, select the following models:
    Group box Model
    Space Three Dimensional
    Time Steady
    Material Solid
    Optional Models Solid Stress
    Enabled Models Material Law Models (selected automatically)
The default solid material, Al, is appropriate to this case.

Define the material law that approximates the behavior of the material. In this tutorial, you model the material as isotropic linear elastic:

  1. Expand the Continua > Plate Physics > Models > Material Law Models > Material Laws node.
  2. Rename the Material Laws > Default Material Law node to Isotropic Linear Elastic.
  3. For the Isotropic Linear Elastic law node, select the following models:
    Group box Model
    Material Stiffness Models Linear Elasticity
    Material Strain Measures Linear Strain (Small Strain) (selected automatically)
    Linear Elastic Material Models Isotropic Linear Elasticity
  4. Expand the Plate Physics > Models > Solid > Al > Material Properties > Material Law node.
    By default, Simcenter STAR-CCM+ sets Type to the default material law, Isotropic Linear Elastic.
