Problem description: structural problem                            
The matrix Serena is obtained from a structural problem            
discretizing a gas reservoir with tetrahedral Finite Elements.     
The medium is strongly heterogeneous and characterized by a        
complex geometry consisting of alternating sequences of thin       
clay and sand layers.  Some further information may be found       
in the paper:
