The set of OpenCASCADE kernel functions.
| add_box⚠ | Add a parallelepipedic box defined by a point (x, y, z) and the
extents along the x-, y- and z-axes. If tag is positive, set the tag
explicitly; otherwise a new tag is selected automatically. Return the tag
of the box.
|
| add_curve_loop⚠ | Add a curve loop (a closed wire) formed by the curves curveTags.
curveTags should contain tags of curves forming a closed loop. Note that
an OpenCASCADE curve loop can be made of curves that share geometrically
identical (but topologically different) points. If tag is positive, set
the tag explicitly; otherwise a new tag is selected automatically. Return
the tag of the curve loop.
|
| add_line⚠ | Add a straight line segment between the two points with tags startTag and
endTag. If tag is positive, set the tag explicitly; otherwise a new tag
is selected automatically. Return the tag of the line.
|
| add_plane_surface⚠ | Add a plane surface defined by one or more curve loops (or closed wires)
wireTags. The first curve loop defines the exterior contour; additional
curve loop define holes. If tag is positive, set the tag explicitly;
otherwise a new tag is selected automatically. Return the tag of the
surface.
|
| add_point⚠ | Add a geometrical point in the OpenCASCADE CAD representation, at
coordinates (x, y, z). If meshSize is > 0, add a meshing constraint
at that point. If tag is positive, set the tag explicitly; otherwise a
new tag is selected automatically. Return the tag of the point. (Note that
the point will be added in the current model only after synchronize is
called. This behavior holds for all the entities added in the occ module.)
|
| add_sphere⚠ | Add a sphere of center (xc, yc, zc) and radius r. The optional
angle1 and angle2 arguments define the polar angle opening (from -Pi/2
to Pi/2). The optional angle3 argument defines the azimuthal opening
(from 0 to 2*Pi). If tag is positive, set the tag explicitly; otherwise a
new tag is selected automatically. Return the tag of the sphere.
|
| add_torus⚠ | Add a torus, defined by its center (x, y, z) and its 2 radii r and
r2. If tag is positive, set the tag explicitly; otherwise a new tag is
selected automatically. The optional argument angle defines the angular
opening (from 0 to 2*Pi). Return the tag of the wedge.
|
| remove_point⚠ | Remove the entities dimTags. If recursive is true, remove all the
entities on their boundaries, down to dimension 0.
|
| synchronize⚠ | Synchronize the OpenCASCADE CAD representation with the current Gmsh model.
This can be called at any time, but since it involves a non trivial amount
of processing, the number of synchronization points should normally be
minimized.
