CFX! Introduction CEL-CFX Expression language 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) Can use built-in mathematical functions Can be used on any form which has an Expression Editor button Examples to use CeL Complex boundary conditions Variable material properties Variable initial conditions Extra terms to the governing equations 5.5 2001AEA TechnologyCFX 5.5 © 2001AEA Technology 4-2 Introduction CEL - CFX Expression Language. - 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). - Can use built-in mathematical functions. - Can be used on any form which has an Expression Editor button. - Examples to use CEL: > Complex boundary conditions. > Variable material properties. > Variable initial conditions. > Extra terms to the governing equations
