PROTEUS twodimensional NavierStokes computer code, version 1.0. Volume 2: User's guide
Abstract
A new computer code was developed to solve the twodimensional or axisymmetric, Reynolds averaged, unsteady compressible NavierStokes equations in strong conservation law form. The thinlayer or Euler equations may also be solved. Turbulence is modeled using an algebraic eddy viscosity model. The objective was to develop a code for aerospace applications that is easy to use and easy to modify. Code readability, modularity, and documentation were emphasized. The equations are written in nonorthogonal bodyfitted coordinates, and solved by marching in time using a fullycoupled alternating directionimplicit procedure with generalized first or secondorder time differencing. All terms are linearized using secondorder Taylor series. The boundary conditions are treated implicitly, and may be steady, unsteady, or spatially periodic. Simple Cartesian or polar grids may be generated internally by the program. More complex geometries require an externally generated computational coordinate system. The documentation is divided into three volumes. Volume 2 is the User's Guide, and describes the program's general features, the input and output, the procedure for setting up initial conditions, the computer resource requirements, the diagnostic messages that may be generated, the job control language used to run the program, and several test cases.
