| Since the melt velocity is decoupled from the McKenzie equations, it is relatively simple to calculate, provided that the pressure and solid velocity fields have already been accurately determined. As such no tests were applied to validate its accuracy, however qualitatively their behavior is observed to be correct. | Since the melt velocity is decoupled from the McKenzie equations, it is relatively simple to calculate, provided that the pressure and solid velocity fields have already been accurately determined.
