  • nlmesh line
  • Figure 1 - nLMesh Line Mesh

Purpose: This interface is for shell mesh generation using curves. The following methods are available:

  • 2 line Shell - Create a mesh between 2 lines
  • 3 line Shell - Mesh a region bounded by 3 lines
  • 4 line Shell - Mesh a region bounded by 4 lines
  • Line Sweep - Create a mesh by sweeping one line along another line

This interface is often useful in cases where a topology mesher leaves holes due to missing CAD surface data

Controls:

  • Type: 2 Line Shell, 3 Line Shell, 4 Line Shell
  • rbs Number of Elements - Mesh by number of elements
  • rb Element Size - Mesh by element size
  • rb Point of Line - Mesh by existing points of line

  • N1: Enter or adjust number of elements along line 1
  • N2: Enter or adjust number of elements along line 2
  • N3: Enter or adjust number of elements along line 3
  • N4: Enter or adjust number of elements along line 4

  • Part Id: Enter or select target part ID

  • nlmesh sweep
  • Figure 2 - nLMesh Line Sweep
  • Type: Line Sweep
  • rbs Number of Elements - Mesh by number of elements
  • rb Element Size - Mesh by element size
  • rb Point of Line - Mesh by existing points of line

  • N1: Enter or adjust number of elements along cross section
  • N2: Enter or adjust number of elements along sweep path

  • cb Keep Angle - Keep the angle between the cross section and sweep path
  • cbc Keep Cross-section - Keep the elements from cross-section

  • Part Id: Enter or select target part ID
