Functions to visualize the geometry elements and numbering and orientation of their facets (edges and faces).
The standard geometry elements can be plotted by running:
$ python sfepy/postprocess/plot_facets.py
draw_arrow(ax, coors, angle=20.0, length=0.3, **kwargs)¶
Draw a line ended with an arrow head, in 2D or 3D.
plot_edges(ax, gel, length)¶
Plot edges of a geometry element as numbered arrows.
plot_faces(ax, gel, radius, n_point)¶
Plot faces of a 3D geometry element as numbered oriented arcs. An arc centre corresponds to the first node of a face. It points from the first edge towards the last edge of the face.
Plot a geometry element as a wireframe.
