NACHOS: a finite element computer program for incompressible flow problems. Part II. User's manual
The NACHOS computer code is a general purpose computer program designed for the solution of two dimensional, incompressible fluid dynamics problems. The solution method used in NACHOS is based on the finite element method (FEM). The class of problems treated by the present version of NACHOS are those described by the two dimensional (plane or axisymmetric), incompressible form of the Navier-Stokes equations. An energy equation is also included in the formulation for problems in which heat transfer effects are important. Among the specific types of flow problems for which NACHOS is suitable are the following: isothermal flow problems; forced convection problems; free convection problems; mixed convection problems; and convection problems including solid body heat conduction effects. NACHOS readily accepts either transient or steady state forms of the above problems. The program capabilities and organization are discussed. A detailed description of the input data necessary to access and execute the NACHOS code is presented. Several example problems are provided to illustrate the use of the program. (LCL)
