fedoo.mesh.thicken

thicken(mesh, thickness, n_nodes=2, normal=None, name='')

Create a solid by thickening a surface mesh along nodal normals.

Parameters:

  • mesh (fedoo.Mesh) – Two-dimensional surface mesh to thicken. tri3 and quad4 elements are supported.

  • thickness (float or tuple[float, float]) – With a positive scalar, the original surface is the midsurface and the offsets are (-thickness/2, thickness/2). A two-value tuple gives the lower and upper offsets explicitly.

  • n_nodes (int, default=2) – Number of nodes through the thickness.

  • normal (array_like, optional) – One 3D normal vector, or one vector per surface node. Without this argument, area-weighted nodal normals are computed from the adjacent surface elements.

  • name (str, optional) – Name of the generated solid mesh.

Returns:

Solid mesh made of wed6 or hex8 elements.

Return type:

fedoo.Mesh

Notes

The input surface must have consistently oriented elements. Large thicknesses or highly curved surfaces may produce intersecting or inverted solid elements; no geometric collision correction is performed.
