A finite-difference procedure which requires the use of ยจirtual and duplicate nodes is presented. This procedure incorporates the Neumann and Dirichlet boundary conditions into the two-dimensional Helmholtz equation. Comparisons made with analytic solutions for waยจeguide modes indicate that robust s

โฆ Synopsis
A new simpler solution procedure is presented for the finite element analysis of creep problems. The creep strains are eliminated as computation variables. At each time step, a system is solved for the stresses and velocities alone.

An implicit unconditionally stable partitioned solution procedure for the simultaneous integration of transient coupled ยฎeld problems is presented. The procedure does not require that the full system of coupled equations be assembled, and allows use of existing single-ยฎeld analysis software modules
