This component takes a 3D volumetric mesh as input and updates its vertices' coordinates to improve a trade-off between element quality and the fitting to various geometric targets. The geometric target is defined through an oracle that for each "boundary" element returns the tangent space it should align to. The smoothing process will iteratively relocate the vertices of the mesh to best fit these targets while improving the quality of the elements. The final result is guaranteed to remain free of inverted elements from a valid input. Starting from an invalid mesh, the algorithm will attempt to untangle it and recover a valid configuration.
