Abstract: In many stages of a typical computational simulation, the user has a requirement to extract data which is not always in a readily available form. Typical examples include mesh quality statistics, where the quality measure is typically defined using an expression involving the co-ordinates of each mesh cell, face, edge or node; solution visualisation, where the quantity to be displayed/analysed is an expression involving the resultant variables of the flow solver; and mesh adaption, where the refinement may be driven by a quantity which could be a combination of flow solution variables and the co-ordinates of the mesh edges. A code developer can readily modify source code to meet such requirements but this is not an option to a typical user and, when additionally, codes are embedded within graphical user interfaces. This paper describes EQUATE, a system designed to allow the user to define their own measures at run-time, and how it can be integrated into general interactive, graphical environments.
