Group Chen

Group Description
Finite element matrices from Pu Chen, Peking University.

14 symmetric positive-definite matrices (patterns only).

Except for pkustk07, pkustk08, and pkustk13, all problems
arose in civil engineering.  There is more than 1 degree
of freedom at each node in the finite-element mesh.

pkustk07 and pkustk08 are regular 3D meshes, with one side fixed
in the original FE models.
