% Surface mount transistor, 1704 reduced triquadratic elem, therm stress.
% This is a stiffness matrix from a thermal stress analysis of           
% a surface mounted transistor.  Due to symmetry only one half of        
% the model is discretized in 1704 standard reduced triquadratic elements
% (20 node serendipity).  There are 5 different materials.               
% The stiffness matrix is integrated by 3x3x3 Gaussian quadrature.       
% Separate load vector file is also available.                           
% Figure of the FE model can be seen in a separate description,          
% or downloaded as a postscript file from the contributors www-pages.
