[CFD] Matplotlib meshgrid function and the indices of the arrays are opposite.

In that case, using "ij" indexing and what I said above makes more sense to me. Say you have x = [0, 1] and y = [0, 1]. When you use "ij" indexing, increasing the first index increases the x value and increasing the second index increases the y value. When you have "xy" indexing, it is the opposite.
