See user's guide in version 4.2.

P1+P1 is first order elements for velocity and first order elements for pressure
P2+P1 is second order elements for velocity and first order elements for pressure
P3+P2 is third order for velocity and second order for pressure

See user's guide in version 4.2. P1+P1 is first order elements for velocity and first order elements for pressure P2+P1 is second order elements for velocity and first order elements for pressure P3+P2 is third order for velocity and second order for pressure
