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.
  - Define Surface Mesh Size
    Use the Surface tool to define local mesh settings on selected surfaces.
  - Define Edge Mesh Size
    Use the Edge tool to define local mesh settings on selected edges.
  - Define Edge Layer Mesh Controls
    Use the Edge Layer tool to generate layers from selected edges during surface meshing.
  - Define Gap Based Refinement Criteria
    Use the Gap tool to define mesh refinement settings based on gaps between surfaces.
  - Define Angle Based Refinement Criteria
    Use the Angle tool to define mesh refinement settings based on angles between surfaces.
  - Define Boundary Layer Settings
    Use the Boundary Layer tool to define boundary layer mesh settings on selected surfaces.
  - Define Volume Mesh Local Settings
    Use the Volume Mesh tool to define local volume mesh sizes on individual solids. You can also choose different volume mesh settings, such as defining layers on thin regions and quality controls.
  - Define Mesh on Extruded Geometry
    Use the Extrusion tool to create hex mesh on extruded geometry. This is useful for creating mesh for 2D simulations and layered mesh on simplified geometry.
  - Create Zone Mesh
    Use the Zones tool to define mesh refinement settings by shape. These controls provide the capability to get mesh refinement on surfaces enclosed in defined boxes, spheres, and cylinders.
  - Define Advanced Mesh Settings
  - Define Surfaces with No Boundary Layer
    Use the No Boundary Layer tool to define surfaces on which boundary layers should not be created nor imprinted.
  - Define Mesh Controls Using Groups
    Use the Advanced Create dialog in the Setup Browser to create mesh controls for selected entity groups.
  - Deactivate Mesh Controls
    Use the context menu on the legend to deactivate mesh controls. This excludes them from consideration when processing the solution.
- 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.
- 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.

Define Edge Mesh Size

Use the Edge tool to define local mesh settings on selected edges.

Select the surfaces on which to apply the mesh control in the following ways:
- While in the Mesh ribbon, select edge lines, then right-click and select Assign Mesh Controls > Edge from the context menu.
- From the Mesh ribbon, click the Edge tool.
  Figure 1.
  
  Select edge lines.
In the dialog, enter an average element size.
From the guide bar, execute the command in the following ways:
- Click to confirm your selection and remain in the tool.
  This allows you to continue creating instances and helps you visualize and edit instances with the legend.
- Click to confirm your selection and exit the tool.
