Structuring preconditioners for unstructured meshes
Copyright policy )Structuring preconditioners for unstructured meshes
The authors develop a fictitious space technique for the construction of preconditioners for stiffness matrices generated by the finite element method using unstructured meshes. A comparison of the results of numerical experiments for the above preconditioners is also made.
