Dyadic product in COMSOL?

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...

What is the role of little Fe impurity (0.2wt.%) in the grain refinement of commercial purity Al compared with that of high purity Al (99.999%)?

Commercial purity Al usually contains little impurities, mainly Fe (0.2wt.%) and a little Si. However, such little impurities can have an obvious influence on the grain refinement compared to that...
