Detailed Description

Demonstration of IgANet function fitting on a geometry loaded from a file.

Author

Veronika Travnikova

This example demonstrates how to implement an IgANet to fit a given function on a geometry loaded from a file. In contrast to the example iganet_fitting_geometry_simple.cxx this examples makes use of pre-computed indices and coefficients and should therefore be faster. This example can be configured with the following environment variables

IGANET_NCOEFFS - number of B-spline coefficients IGANET_NLAYERS - number of network layers IGANET_NNEURONS - number of neurons per layer IGANET_MAX_EPOCH - maximum number of epochs during training IGANET_MIN_LOSS - tolerance for loss function
