Regularises the given field using a PDE smoother and then sharpens (projects) the result using a smoothed Heaviside function. Used in topology optimisation to regularise the designed geometries and obtain 'grid independent' solutions.
Largely follows the PDE-based smoothing of Lazarov, B. S., & Sigmund O. (2010). Filters in topology optimization based on Helmholtz-type differential equations. International Journal for Numerical Methods in Engineering, 86(6), 765-781. https://doi.org/10.1002/nme.3072
