Meshless techniques for anisotropic diffusion

Annamaria Mazzia, Giorgio Pini, Flavio Sartoretto
2014 Applied Mathematics and Computation  
A good numerical method would be locally mass conservative, produce no or minimal over/under-shoots, produce minimal numerical diffusion, and require no CFL time-step limit for stability.  ...  Moreover, it would be good for the methods to be of high order accuracy.  ...  We show how to solve the equations using a global implicit approach in an efficient way, and we present the derived computational results.  ...
