Intrepid: /usr/src/RPM/BUILD/trilinos-11.12.1/packages/intrepid/example/Drivers/example

Construction of Laplace operator on a uniform hexahedral mesh using arbitrary-degree elements. This is the most naive implementation wherein we form the stiffness matrix on each cell by quadrature and do not preallocate the global matrix graph before assembling. More...

Detailed Description

    div grad u = f in Omega
    u = 0 on Gamma 

    Discrete linear system for nodal coefficients(x):
        
    Kx = b

    K - HGrad stiffness matrix
    b - right hand side vector
