Steps

Steps provide an ordered sequence of mesh workflow operations for the selected mesh workflow type. Each Step represents controls and outputs defined for the specific operation. A set of control data defines each Control based on its specific operation control type. Outcomes are predefined to collect desired outputs after running the operation. The major purpose of Outcomes, besides monitoring results, is also to collect output information which can be used as input for a subsequent operation.

Right-click options available in the Steps are:

  • Revert To Last Checkpoint: Allows you to revert to the step where the last checkpoint is enabled.

  • Execute Step: Executes the next step of specific Mesh Workflow. Execute Step is available only when Input is scoped. If the mesh workflow is not initialized yet, Execute Step initializes the workflow before executing the step.

  • Execute All Steps: Executes all steps of specific Mesh Workflow. Execute All Steps is available only when Input is scoped. If the mesh workflow is not initialized yet, Execute All Steps initializes the workflow before executing the step.

  • Enable All Checkpoints: Allows you to enable checkpoints for all operations that are not executed. Enable All Checkpoints option is available only when at least one checkpoint is disabled for an operation that is not executed.

  • Disable All Checkpoints: Allows you to disable checkpoints for all operations that are not executed. Disable All Checkpoints option is available only when at least one checkpoint is enabled for an operation that is not executed.

  • Clear Checkpoint Data: Allows you to clear all checkpoint data for the executed mesh workflow operation and sets Create Checkpoint to No for all operations in the workflow.

  • Propagate Settings: Transfer mesh settings when you update some sizes or number of layers associated with individual steps in the Mesh Workflows. The available option is:

    • Acoustic Settings: Transfer acoustic mesh settings when you update some sizes or number of layers associated with individual steps in the Mesh Workflows.

    • Stacker Settings: Transfer stacker settings when you disconnect sizes or tolerance attributes associated with individual steps in the Mesh Workflows. Stacker Settings is available only for the stacker workflows.

    Note:  Propagate Settings is available only when you define all options in the Steps Details view.

  • Insert: Allows you to insert mesh workflow steps. You can only Insert a mesh workflow step if the Output node is not completed.

  • Delete Steps and Clear Data: Allows you to delete all steps and clear data in the workflow. When you click Delete Steps and Clear Data for the specified mesh workflow, the Input node remains scoped and you can select the Mesh Workflow Type for the Mesh Workflow.

  • Rename: Allows you to rename the Steps.

Steps Details view has the following options:

    When Quadratic Elements is No, the default value for Number of PMLs/IPMLs is 4.

    When Quadratic Elements is Yes, the default value for Number of PMLs/IPMLs is 2.

    Note:   Number of Acoustic Layers and Number of PMLs/IPMLs are only available for External FEM Acoustic workflow.

  • Mesh Size: Displays the mesh size for the mesh workflow. Mesh Size is a read-only value calculated based on the following formula:

    wavelength = C/F

    C = Speed of Sound, and

    F = Analysis Frequency

    For linear elements,

    Mesh Size = wavelength/12

    For quadratic elements,

    Mesh Size = wavelength/6
