calc4fem: Open-Source Finite Element Analysis Calculator
calc4fem is an open-source finite element analysis calculator and solver for various physics and engineering applications, featuring a basic GUI and scripting functionality.
What is Calc4fem?
calc4fem is an open-source, cross-platform finite element analysis program focused on providing core FEA functionality for common engineering applications. It features a basic graphical user interface for pre- and post-processing along with Python scripting capabilities for automating workflows.
Some of the key capabilities and features of calc4fem include:
- Linear static, modal, harmonic, and transient analysis for structural mechanics and heat transfer.
- Common element types such as trusses, beams, shells, membranes, plane stress/strain, axisymmetric, and 3D solids.
- Various material models including linear elastic, hyperelastic, plasticity, and thermal conduction.
- Handles triangles, quadrilaterals, tetrahedrals, wedges, and hexahedral mesh elements.
- Prescribed boundary conditions and applied loads including forces, pressures, temperatures, and enforced displacements.
- Automated geometry and meshing modules powered by Gmsh.
- Visualization of undeformed meshes, deformed solutions, contour plots, animated mode shapes, and X-Y graphs.
- Scripting interface for complete control over model definition, solution, and results post-processing.
- File importing/exporting for integrating with CAD and CAE workflows.
- Open source (LGPL) allowing customization and integration into proprietary programs.
While having fewer features than commercial codes, calc4fem provides a lightweight, hackable, and extensible platform for common finite element modeling needs for research and industry applications.
