 # BforStrain
 These codes compute strain rates on a trianglular 2D mesh using a geodetic velocity field. The method is based on the paper by K. Johnson (2024) available at https://doi.org/10.1029/2023JB027472 . Body-forces in a thin elastic plate are used to compute a velocity and strain rate field computed at the centroids of the triangles in the mesh.  The inversion solves for the distribution of body forces (at the triangle nodes) that best-fits the geodetic velocity field.  You can specify a range of smoothing values (called beta) that minimize the magnitude of the body forces. There is also an optional second step that further minimizes strain rates below a specified threshold.
