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.
