CFX! Introduction 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 and momentum s Solid sub-domains: conjugate heat transfer Cutouts and sub-domains are defined using existing solids Domain/sub-domains are used to define the physical models and physical properties for the CFX-5 simulations CFX5.5 V5.5.1H 2001AEA TechnologyCFX 5.5 V5.5.1H © 2001AEA Technology 5-2 Introduction 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 and momentum * Solid sub-domains: conjugate heat transfer > Cutouts and sub-domains are defined using existing solids Domain/sub-domains are used to define the physical models and physical properties for the CFX-5 simulations
