This page is devoted to frequently asked questions (FAQ) related to meshing.

On this page:

To connect meshes, what is the advantage of using line constraints and not mesh generators?

Answer: Mesh generators tend to distort elements, which either reduces solution accuracy or requires a more refined mesh to achieve certain levels of accuracy. Line constraints prevent element distortion, which minimizes the amount of meshing, and enables efficient and accurate formulation.

While meshing shell elements, how can I prevent the "Meshing Failed" error message?

Answer: To resolve, try using different mesh sizes or [subdividing] the object into more regular shapes. When modeling shells, it is often helpful to avoid certain shapes, including those with:

  • Corners close to zero or 180 degrees
  • Large differences in the length of certain edges

Why do my shell elements appear to be meshed though I am not assigning an auto-mesh?


Unknown macro: {new-tab-link}


Software automatically uses general meshing to mesh any areas drawn using more than four joints. To avoid meshing when no auto-meshing has been assigned, [subdivide] the object such that each region has four joints or less.
