calfem.vis_mpl.draw_displacements¶

Purpose:

Draws scalar element values in 2D or 3D. Returns the world object elementsWobject that represents the mesh.

Syntax:

cfv.draw_displacements(a, coords, edof, dofs_per_node, el_type, draw_undisplaced_mesh=False, magnfac=-1.0, magscale=0.25, title=None, color=(0, 0, 0), node_color=(0, 0, 0))

Description:

Source docstring:

Draws scalar element values in 2D or 3D. Returns the world object
elementsWobject that represents the mesh.

Parameters
----------
ev : array_like
    An N-by-1 array or a list of scalars. The Scalar values of the elements. ev[i] should be the value of element i.
coords : array_like
    An N-by-2 or N-by-3 array. Row i contains the x,y,z coordinates of node i.
edof : array_like
    An E-by-L array. Element topology. (E is the number of elements and L is the number of dofs per element)
dofs_per_node : int
    Dofs per node.
el_type : int
    Element Type. See Gmsh manual for details. Usually 2 for triangles or 3 for quadrangles.
displacements : array_like
    An N-by-2 or N-by-3 array. Row i contains the x,y,z  displacements of node i.
axes : matplotlib.axes.Axes
    Matlotlib Axes. The Axes where the model will be drawn. If unspecified the current Axes will be used, or a new Axes will be created if none exist.
draw_undisplaced_mesh : bool
    True if the wire of the undisplaced mesh should be drawn on top of the displaced mesh. Default False. Use only if displacements != None.
magnfac : float
    Magnification factor. Displacements are multiplied by this value. Use this to make small displacements more visible.
title : str
    Changes title of the figure. Default "Element Values".
