Computational Fluid Dynamics (CFD) Simulation of fluid flow, heat transfer and mass transfer processes CFD involves the numerical solution of the governing equations Mass continuity

Main Objective: Build a viable domain (B-rep solids, cutout solids, simple solids) B-rep (Boundary Representation) solids are composed of simple and/or trimmed surfaces Simple (Parametric) solids have cubic topology Multiple solids must connect at whole faces Surface and face congruency and parameterization must be kept in mind or the mesh quality will suffer

Domains represent 3D regions where governing equations are solved Domains can be comprised of more than one solid joined together Domains can also contain internal 3D regions Cutouts- solid obstacles to flow Sub -domains- Fluid sub-domains: volumetric sources/sinks of mass. heat

Create a solid which defines the region of interest. Define the fluid domain in terms of flow region, physical models, and fluid properties. Apply boundary conditions to fluid domain surfaces. Specify an initial guess/condition for the simulation

CEL is an interpreted, declarative language which enables users to enhance simulations without recourse to external fortran routines. It uses mathematical expressions for physical quantities as opposed to using fixed values. Access to CFX-5 internal variables (including solution variables)

Boundary conditions are required to set on all external domain boundaries Initial values/guess are required to set for all calculations Boundary conditions and initial values/guess can be either constants or expressions
