Williams, W A; Wilson, D G

This report documents IMPSOR, a FORTRAN code that implements finite difference methods for multidimensional moving boundary problems with Dirichlet or Neumann boundary conditions on a Cray X-MP. The geometry of the spatial domain is a rectangular parallelepiped. The dimensions of the parallelepiped are specified by the user. Dirichlet or Neumann boundary conditions may be specified on each face of the box independently. The initial conditions are arbitrary. The user defines the initial and boundary conditions as well as the thermal and physical properties of the problem. Additionally, several parameters of the numerical method, e.g., degree of implicitness, time step size, are also specified by the user.
