dbo:abstract
  • In computer aided engineering (CAE) a preprocessor is a program which provides a graphical user interface (GUI) to define physical properties. This data is used by the subsequent computer simulation. Steps that are followed in Pre-Processing 1> The geometry (physical bounds) of the problem is defined 2> The volume occupied by the fluid is divided into discrete cells (meshing) 3> The physical modeling is defined - E.g. equations of motion + enthalpy + radiation + species conservation 4> Boundary conditions are defined. This involves specifying the fluid behavior and properties at the boundaries of the problem. For transient problems, the initial conditions are also defined. 5> The simulation is started and the equations are solved iteratively as a steady state or transient 6> Finally a post-processor is used for the analysis and visualization of the resting solution * v * t * e (en)
