Plane or axisymmetric advection-diffusion

For the axisymmetric element, the symmetry axis is Y.

The element is defined by 4 nodes specified in NODES following the order indicated in the figure.

The element must be used with law ADVEC

The resolution method is the UPWIND FUPG method (with second order derivatives of the interpolation functions). The time discretization must therefore be small enough (Courant number less than unity) but the mesh can be more distorted than for the element CONV2 (that element is not in the Lagamine manual but it exists in the code).

In case of a dissipation problem, oscillations can persist.
