Dear all,

This is my first post in this forum! which i think its a great place to share knowledge with scientists.

My question is, could some please explain the diffrence between Finite Element Method (FEM) and Mixed-Finite Element Method (Mixed-FEM)?

I have been researching FEM to use in reservoir simulation. And heard that a better method is Mixed-FEM becuase it gives a better conservation of mass for Flow dynamics (FD) problem. could someone kindly give the advantages and disadvantages of each for FD problems.

thanx in advance.
