3D Grid Validation

Intro

Validating 3D frame nodal displacement and reactions with another software

Validate with

OpenSEES (the Open System for Earthquake Engineering Simulation) software (available via http://opensees.berkeley.edu/)

Validate objective

compare nodal displacement from BFE.net library and OpenSEES for a model consist of random 3d bars

Model Definition

  • A 5x5x5 node grid, connected horizontally and vertically by elemetns, with nodes and bar elements.
  • Every node in the model have a random load on it, random displacement in original location.
  • Every node have a random displacement from original location on grid to make test case irregular
  • Every element in the model have a random uniform distributed load on it.

Validation Result

Nodal Displacements

  • Max ABSOLUTE Error: 4.125e-013

Nodal Support Reactions

  • Max ABSOLUTE Error: 4.879e-007

Extra

Code and details available at BriefFiniteElementNet.Validation.BarElementTester.Validation_1() and can be run fromBriefFiniteElement.Validation.Ui project
