6.3.3 Miscellaneous

Here is a list of all other mesh commands currently available:

Point | Line { expression-list } In Surface { expression };

Embed the point(s) or line(s) in the given surface. The surface mesh will conform to the mesh of the point(s) or lines(s).

Surface { expression-list } In Volume { expression };

Embed the surface in the given volume. The volume mesh will conform to the mesh of the surface.

Periodic Line { expression-list } = { expression-list };

Force mesh of lines on the left-hand side (slaves) to match the mesh of the lines on the right-hand side (masters).

Periodic Surface expression { expression-list } = expression { expression-list };

Force mesh of the surface on the left-hand side (slave, with boundary edges specified between braces) to match the mesh of the surface on the right-hand side (master, with boundary edges specified between braces).

Coherence Mesh;

Removes all duplicate mesh vertices.

< Recursive > Color color-expression { Point | Line | Surface | Volume { expression-list }; … }

Sets the mesh color of the entities in expression-list to color-expression.

< Recursive > Hide { Point | Line | Surface | Volume { expression-list }; … }

Hides the mesh of the entities in expression-list, if General.VisibilityMode is set to 0 or 2.

Hide char-expression;

Hides the mesh of the entity char-expression, if General.VisibilityMode is set to 0 or 2 (char-expression can for example be "*").

Recombine Surface { expression-list } | "*" < = expression >;

Recombines the triangular meshes of the surfaces listed in expression-list into mixed triangular/quadrangular meshes. The optional expression on the right hand side specifies the maximum difference (in degrees) allowed between the largest angle of a quadrangle and a right angle (a value of 0 would only accept quadrangles with right angles; a value of 90 would allow degenerate quadrangles; default value is 45).

Reverse Line | Surface { expression-list } | "*" ;

Reverses the mesh of the given line(s) or surface(s).

Save char-expression;

Saves the mesh in a file named char-expression, using the current Mesh.Format (see section Mesh options list). If the path in char-expression is not absolute, char-expression is appended to the path of the current file.

< Recursive > Show { Point | Line | Surface | Volume { expression-list }; … }

Shows the mesh of the entities in expression-list, if General.VisibilityMode is set to 0 or 2.

Show char-expression;

Shows the mesh of the entity char-expression, if General.VisibilityMode is set to 0 or 2 (char-expression can for example be "*").

Smoother Surface { expression-list } = expression;

Sets number of elliptic smoothing steps for the surfaces listed in expression-list (smoothing only applies to transfinite meshes at the moment).

Homology ( { expression-list } ) { { expression-list } , { expression-list } };

Compute a basis representation for homology spaces after a mesh has been generated. The first expression-list is a list of dimensions whose homology bases are computed; if empty, all bases are computed. The second expression-list is a list physical groups that constitute the computation domain; if empty, the whole mesh is the domain. The third expression-list is a list of physical groups that constitute the relative subdomain of relative homology computation; if empty, absolute homology is computed. Resulting basis representation chains are stored as physical groups in the mesh.

Cohomology ( { expression-list } ) { { expression-list } , { expression-list } };

Similar to command Homology, but computes a basis representation for cohomology spaces instead.
