Advanced Software Solutions


Fox Equipment uses the following advanced computer techniques to provide numerical solutions to complicated projects. All of these products are used concurrently to facilitate design optimization by calculating “what if” scenarios.

Fox Equipment’s custom Stack Super Program is used to design, evaluate, size and price steel and fiberglass stacks.

RISA 3D is a numerical design package for simple finite element design problems. Simple pre and post processing routines make Risa 3D perfect for small budget projects. AutoCad can be used to input the problem geometry.

STAAD is a full feature finite element program widely used by structural engineers in a variety of applications. STAAD is selected for pure structural engineering problems consisting of large systems of nodes and elements.

ANSYS is a robust, full featured finite element program which has become the standard in the power generation industry. ANSYS allows the analysis of complex problems faced in power generation like transient thermal analysis and computational fluid dynamics.

FLUENT is now a part of the ANSYS computational suite and the predominant computational fluid dynamics tool for calculating system pressure losses, catalyst and silencer pressure losses and turning vane optimization.
