Inconsistent Stabilization
This section contains a single stabilization method: isotropic diffusion. Adding isotropic diffusion is equivalent to adding a term to the physical diffusion coefficient. This means that the original problem is not solved, which is why isotropic diffusion is an inconsistent stabilization method. Although the added diffusion definitely attenuates spurious oscillations, try to minimize the use of isotropic diffusion.
By default there is no isotropic diffusion. To add isotropic diffusion, select the Isotropic diffusion check box. The field for the tuning parameter δid then becomes available. The default value is 0.25; increase or decrease the value of δid to increase or decrease the amount of isotropic diffusion.
