Visualization tool for FElupe

FEplot

A visualization tool for FElupe.

FEplot is based on the popular visualization library matplotlib which is used generally to create 2D plots. The fantastic thing that comes with FEplot is that matplotlib becomes able to plot 3D volume FEA results.

Setup

To run this project, you can easily install it locally using pip:

pip install feplot

All is ready now, let's move on!

How to Use

Starting with a quick example:

import felupe as fem
from feplot.pylab import Plotter 

# create a hexahedron-region on a cube
mesh = fem.Cube(n=11)
region = fem.RegionHexahedron(mesh)

# add a field container (with a vector-valued displacement field)
field = fem.FieldContainer([fem.Field(region, dim=3)])

# apply a uniaxial elongation on the cube
boundaries = fem.dof.uniaxial(field, clamped=True)[0]

# define the constitutive material behaviour 
# and create a nearly-incompressible (u,p,J - formulation) solid body
umat = fem.NeoHooke(mu=1)
solid = fem.SolidBodyNearlyIncompressible(umat, field, bulk=5000)

# prepare a step with substeps
move = fem.math.linsteps([0, 1], num=10)
step = fem.Step(
    items=[solid], 
    ramp={boundaries["move"]: move}, 
    boundaries=boundaries
)

# add the step to a job, evaluate all substeps
job = fem.Job(steps=[step])
job.evaluate()

# initialize plotter 
pl = Plotter()
# plot displacements results (X-Axis)
pl.plot_displacement(field, label='U$_1$', component=0)
# hide grid
pl.hide_grid()

Here are some other features:

# set view to XY-Plane
pl.xy_view()
# add ruler (only for X-Axis)
pl.show_ruler(1, 0, 0)
