I checked the source file for the INSAMass kernel and it seems call the INSADMaterial. The latter needs two variables which are velocity and pressure.
I feel confused why the variable in the continuity equation is pressure. Additional informationNo response |

You can write the incompressible Navier-Stokes equations in a matrix notation (with operators as the blocks):

parameter in the kernel definition will determine where the residual entries go in the nonlinear system. You see by (just doing R=matrix*sol-rhs for example) that the residual from
