The RBF Collocation Method to Design a Digital Twin for Coffee Percolation
Espresso coffee extraction is a complex physico-chemical process and can be modeled through a system of coupled partial differential equations. We present a numerical solution based on a meshless Collocation Method using Radial Basis Functions and Kansa's approach, which reveals to be accurate and robust in comparison to a reference numerical solution provided by a well-known simulation software.
