FeView: Finite element model (FEM) visualization and post-processing tool for OpenSees

FeView (v1.0) Interface introduces a graphical user interface (GUI) for the popular open source finite element software OpenSees.

Interactive Interface:

Render view of a 20 story building

Deformation shape with undiform wire mesh view

Programming Language

Python 3.7

Dependencies and its insrallation:

  1. PyQt5==5.15.0
  2. PyVista==0.25.3 & pyvistaqt==0.1.1

Recorder setting:

For 2D problem

recorder Node -file Node_displacements.out -time -nodeRange $1stNode $lastNode -dof 1 2 disp
recorder Node -file Node_rotations.out -time -nodeRange $1stNode $lastNode -dof 3 disp
recorder Node -file Node_forceReactions.out -time -nodeRange $1stNode $lastNode -dof 1 2 reaction
recorder Node -file Node_momentReactions.out -time -nodeRange $1stNode $lastNode -dof 3 reaction
recorder Node -file Node_accelerations.out -time -nodeRange $1stNode $lastNode -dof 1 2 accel
recorder Node -file Node_velocities.out -time -nodeRange $1stNode $lastNode -dof 1 2 vel

For 3D problem

recorder Node -file Node_displacements.out -time -nodeRange $1stNode $lastNode -dof 1 2 3 disp
recorder Node -file Node_rotations.out -time -nodeRange $1stNode $lastNode -dof 4 5 6 disp
recorder Node -file Node_forceReactions.out -time -nodeRange $1stNode $lastNode -dof 1 2 3 reaction
recorder Node -file Node_momentReactions.out -time -nodeRange $1stNode $lastNode -dof 4 5 6 reaction
recorder Node -file Node_accelerations.out -time -nodeRange $1stNode $lastNode-dof 1 2 3 accel
recorder Node -file Node_velocities.out -time -nodeRange $1stNode $lastNode -dof 1 2 3 vel

Note: Current versin of FeView support only nodal responses. User need to define recorder as in above. Just replace $1stNode and $lastNode node as your pboblem.

Mode number:

For eigenvalue analysis as prerequisit of FeView set mode number as>

set numModes 3
