Hi all, I am a new user of Wolfram Mathematica. I need to integrate (numerically of course) generic functions above complex 2D domains. For example, i would like to find the moments of inertia of an airfoil cross-section. Is it possible? My idea was to import a triangular mesh (list of nodes and element connectivity) of the integration domain. Then integrate my functions using a trapezoidal integration. How could i do this? Thank you very much, Alfonso
