fmesher: Triangle Meshes and Geometry Tools for Finite Element Calculations

The fmesher library provides tools for generating planar and spherical triangle meshes and performing finite element calculations on 1-, 2-, and 3-dimensional manifolds. It includes methods for handling lines, polygons, and coordinate reference systems, with core code originally part of the 'INLA' package. The implementation is based on concepts from the textbook 'Triangulations and Applications' by Hjelle and Daehlen (2006).

Use Cases

• Generate planar and spherical triangle meshes for spatial analysis based on the mesh generation capabilities described.
• Perform finite element calculations on flat and curved manifolds based on the described support for 1D, 2D, and 3D spaces.
• Transform and handle coordinate reference systems for geospatial data based on the transparent CRS handling mentioned.
• Process lines and polygon geometries for integration with 'sf' and 'sp' packages based on the described interoperability.

Strengths

• Implements methods from the established textbook 'Triangulations and Applications' (Hjelle and Daehlen, 2006).
• Core library code was originally developed and tested within the widely used 'INLA' package for spatial statistics.
• Supports calculations for 1-, 2-, and 3-dimensional flat and curved manifolds, indicating a range of dimensional applications.

Limitations

• Row count, file formats, and dataset size are unknown, which may limit suitability assessment.
