**mesh_quad_parallelepiped

Description

This command is used to quickly generate a ruled mesh of a parallelepiped. You can also refer to mesh_quad_cube. NSETs of the 6 faces (x0, x1, y1, …), of the 12 edges (x0y0, x0y1, x0z1, …) and of the 8 corners (x0y0z0, x0y0z1, …) are automatically generated by default.

*ncutx, ncuty, ncutz

Number of subdivisions along the \(x\), \(y\) and \(z\) axes.

*nb_nodes

Approximate number of nodes. It is an alternative to *ncutx,  ncuty, ncutz.

*sizex, sizey, sizez

Length of the box in each direction.

*elset_cutx, *elset_cuty, *elset_cutz

The number of elset cuts in each direction (for domain decomposition).

*biasx, biasyi, biasz

Geometric progressions parameters that drive the element size from lower to higher coordinates. Do not use bias[xyz] and min_h[xyz] together.

*min_hx, min_hy, min_hz

An other way to set geometric progressions that drive the element size from lower to higher coordinates. Do not use bias[xyz] and min_h[xyz] together.

*no_sets

The faces, edges and corner NSETS are not generated.

*nbyarnsx, *nbyarnsx, *nbyarnsx

The number of “yarns” (fake composite material) in each direction.

*radius_yarns

The size of yarns.
