A Finite Element library for Static and Linear analysis of solids and structures 100% in C#.
Brief Finite Element Dot NET (BFE.NET) is a .NET based software framework for static and linear Finite Element Analysis (FEA) of solids and structures. BFE.NET help you to simply take advantage of Object Oriented approach to analyze FE models. Advantage of such a framework is that user does have a very powerful control on what he is working with, and control is not limited to an UI with predefined controls.
This project is using/used these projects/files:
- CSParse.NET and some other codes from Christian Woltering for solving sparse linear system
- Helix 3D Toolkit for 3D visualizations
- Formulation of considering shear deformation or partial end release in frame elements are ported from Matrix Structural Analysis (MSA) by Dr. Hossein Rahami
- Various Elements (variable node beam, column, truss, shaft, 3 node plate bending and membrane, 4 node tetrahedral)
_ Different loads types (Concentrated force or moment in BarElement body, uniform load on BarElement)
_ Calculate internal force of BarElement at any location of Element.
-
Static Linear analysis (dynamic analysis not fully implemented yet)
-
Supports
LoadCaseandLoadCombinationapproach for analysis and post process -
Considering initial displacements (settlements)
-
Full or partial nodal restrains
-
Compatible with .NET 4.0 and higher
-
All data classes are Serializable
-
Direct and Iterative solvers (More)
-
Good Documentation available at bfenet.readthedocs.io
This library is developed regarding "Code Reuse" so the code will be somehow complicated. There are several types of validation for FE models in this library: Since it is not possible to validate all features with a single software,
-
Unit Test (in project
BriefFiniteElementNet.Tests) -
Validating the result with other well known and open source applications:
-
Validating the result with OpenSees (the Open System for Earthquake Engineering Simulation) available at opensees.berkeley.edu
-
Validating the result with Frame3dd application available at frame3dd.sourceforge.net
-
for more information on validation please have a look at Validation.md file.
for more information on known issues please have a look at know-issues.md file and issues section.
