Dear developers, I have a question for the ordering of unknowns.
For a multicomponent system, such as Navier-Stokes equations, I found that the ordering of unknowns in the system depends on the order of polynomials used for the variables. Take a two-component system with variables u and p for example: -If using first order for both variables, the ordering is point by point, that is u_1, p_1, u_2, p_2, ...., u_n, p_n. -If using second order for u and first order for p, the ordering is field by field, i.e., all the unknowns of u are ordered first then followed by all the unknowns of p. For the second case, is there any way to change to a point by point ordering? Though in such case there is no unknown of p on the mid-edge point.
