1. An apparatus for generating an application data structure, the apparatus comprising: a physical computing system comprising one or more processors, one or more user input devices, a display device, and one or more memory devices, at least one of the one or more memory devices including executable instructions for generating an application data structure, the executable instructions causing at least one of the one or more processors to perform, upon execution, the acts of: embedding a multiphysics model data structure for a physical system in an application data structure, said embedded multiphysics model data structure including at least one modeling operation for said physical system; determining, via at least one of said one or more processors, one or more application features to add to said application data structure, said one or more application features associated with a model of said physical system; adding first data representing at least one form feature for at least one of said one or more application features for said model of said physical system, said first data based on user inputs received via at least one of said one or more input devices; adding second data representing at least one action feature for at least one of said one or more application features for said model of said physical system, said second data based on user inputs received via at least one of said one or more input devices; associating said second data representing said at least one action feature with said least one modeling operation for said physical system to define a sequence of operations for modeling said physical system; and updating said application data structure, said updated application data structure including said added first data, said added second data, and said associating defining said sequence of operations, said updated application data structure being stored on at least one of said one or more memory devices.
