Meshing
Generate surface/volume mesh by defining mesh controls, or interactively create and edit 2D surface mesh.
- Define Mesh Controls
  Use the Mesh Controls tools to define size controls, refinements, and boundary layer controls to be considered for surface and volume meshing.
- Create and Edit 2D Surface Mesh
  Create mesh on individual surfaces interactively and edit elements to fix issues or improve quality.
- Repair Surface Mesh
  Use the Repair tool to find, review, and fix issues in the mesh.
- Create Volume Mesh
  Use the Volume tool to run a surface + volume mesh on the entire model.
- Generate a Mesh Quality Report
  Use the Quality Report tool to check the quality of surface and volume mesh.
- Remove Mesh
  Remove all mesh from the model.
- Review Element Quality
  Use the Element Quality view to review element quality while simultaneously editing your model.
  - How Element Quality is Calculated
    The quality of elements in a mesh can be gauged in many ways, and the methods used often depend not only on the element type, but also on the individual solver used.
  - Review Elements by Quality Index
    Use the QI (Quality Index) Range legend to categorize overall element quality as Worst, Fail, Warn, Good, and Ideal.
  - Review Elements by Element Criteria
    Use the Criteria legend to investigate the model via individual criteria and view a breakdown of all failed and worst elements based on a set QI range. This is useful when you want to resolve criteria violations and evaluate the overall quality of a mesh.
  - Legend Preferences
    The following legend options can be set in File > Preferences > Colors.
- Fix Mesh Quality of Tessellated Models
  Use the Fix tool to improve the quality of an FE (discrete/mesh) model.
Setup
Prepare your model and run the simulation.
Post-Processing
Post-process the simulation results by creating visualizations and measurements.
Automation
Automate simulation processes with templates and utility scripts.
Design Exploration
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Solver Help
More resources for AcuSolve and ultraFluidX solvers.

Review Element Quality

Use the Element Quality view to review element quality while simultaneously editing your model.

The Element Quality view is automatically enabled when creating and editing surface mesh. To manually enable the Element Quality view, click on the View Controls toolbar and select Surface Element Quality.

When the Element Quality view is enabled, elements are colored based on their quality, which is defined by the 2D/3D element criteria settings. A moveable legend displays in the modeling window to assist you in evaluating the element quality. A summary of the model's Compound QI and number/percentage of failed elements is also displayed under the legend.
