FinEtools: Finite Element tools in Julia
FinEtools is a package for basic operations on finite element meshes: Construction, modification, selection, and evaluation of quantities defined on a mesh. Utilities are provided for maintaining mesh-based data (fields), for defining normals and loads, for working with physical units and coordinate systems, and for integrating over finite element meshes.
The package supports application packages, for instance:
- Meshing;
- Meshing of biomedical images;
- Linear acoustics;
- Heat conduction;
- Linear stress analysis;
- Nonlinear stress analysis;
- Analysis of flexible beam and shell structures;
- Vibration in fluids.
