Dyadic product in COMSOL?

09 September 2016 0 3K Report

During the simulation of immiscible alloy solidification, the calculation of Navier-Stokes equation needs the dyadic product of two vectors. I am using the COMSOL software, but cannot use it to complete the calculation.

How to carry out the dyadic product of two vectors in COMSOL?
