      Use the CFD 2D Mesh tool to generate hybrid grids containing hexa/penta/tetra elements in the boundary layer and tetra elements in the core or fare field.
    - Create Panel Mesh
      Use the Panel Mesh tool to generate and edit mapped panel mesh.
    - Create Rigid Body Mesh
      Use the Rigid Body Mesh tool to create a quick mesh to represent the topology of a rigid object.
    - Midmeshing
      Automatically generate a mesh at the midplane location, directly from the input geometry (components, elements, solids or surfaces), without first creating a midsurface.
      - Create Midmesh
        Use the Midmesh: Automatic tool to automatically generate a mesh at the midplane location, directly from the input geometry (components, elements, solids or surfaces), without first creating a midsurface. This saves significant time over the traditional midsurface-based approach.
      - Repair Midmesh Elements or Fill Faces
        Use the Midmesh: Repair/Fill tool to repair midmesh by attempting to fix topological problems (holes/gaps/cracks, intersections, slivers, overlaps) in the mesh and remesh the face, or create a mesh within a closed topology loop, attempting to keep tangency.
      - Create Midedge
        Use the Midmesh: Create Midedge tool to create a midedge.
      - Edit Midmesh Topology
        Use the Midmesh: Edit Topology tool to edit midmesh topology.
      - Align Midmesh
        Use the Midmesh: Align tool to align the midmesh.
      - Inspect Midmesh
        Use the Midmesh: Inspect tool to view/fix nodes deviating from the middle of the geometry, such as Nodes off middle, Nodes off solid edges, Nodes out of solid, Edges off solid edges, and Element centers off middle. The fix corrects the mesh to the mid by node movement or splitting elements.
      - BatchMesher Midmesh Generation Rules
        Midmesh generation is also supported from within BatchMesher.
    - Midsurface
      Extract the midsurface of thin solids, and review and edit midsurface plates.
    - Apply Thickness to Midsurface
      Use the Map Thickness tool to apply thickness values to shell elements on midsurfaced geometry.
    - Rebuild Mesh
      The Rebuild tool streamlines the process of remeshing existing meshes to generate a new mesh with good quality and flow. The rebuild mesh functionality utilizes the same parameter and criteria files used by BatchMesher to define the quality criteria and relevant mesh parameters. This algorithm saves significant time over the traditional automesh and quality correction approach.
    - Adaptive Wrap Meshing
      Adaptive wrap meshing is a useful utility to get a clean, water tight shell mesh out of 2D mesh containing several intersecting parts and small gaps which do not need to be modeled.
    - EM Lattice Meshing
      EM Lattice meshing is a method to create an axis-parallel mesh for 2D and 1D geometry input.
    - Create Facets from Nodes
      Create facets out of a scanned data set or node cloud data.
    - Shrink Wrap Meshing
      Shrink wrap meshing is a method to create a simplified mesh of a complex model when high-precision models are not necessary, as is the case for powertrain components during crash analysis.
