Abstract: A system and method for implementing, on one or more processors, a bidirectional link between a design system and a multiphysics modeling system includes establishing via a communications link a connection between the design system and the multiphysics modeling system. Instructions are communicated via the communication link that include commands for generating a geometric representation in the design system based on parameters communicated from the multiphysics modeling system. One or more memory components can be configured to store a design system dynamic link library and a multiphysics modeling system dynamic link library. A controller can be operative to detect an installation of the design system, and implement via the dynamic link libraries, bidirectional communications of instructions between the design system and the multiphysics modeling system.

Abstract: A graphical user interface includes GUI elements configured for defining discretized base geometry data for a model of a physical system, receiving a first input representing a user instruction to add a perfectly matched layer to the model, receiving a second input representing the user selection of boundaries that define a base geometry, and receiving a third input representing extra geometry meshing instructions. Extra geometry line segment data is discretized representing an outward direction of a PML from the boundary according to the extra geometry meshing instructions. Weak form expressions representing a wave-related phenomena are formed based on received PML settings and physics settings parameterized using discretized base geometry data and discretized extra geometry data. Matrix data are generated based on the formed weak form expressions. A solution to a simulation of the wave-related phenomena of the model is generated based on the formed weak form expressions. A graphical representation of the solution is generated for display on the GUI.

Abstract: A system generates a customized application data structure for modeling physical systems. The system includes a processor, an input device, optionally a display device, and a memory device. The processor is adapted to embed a multiphysics model data structure in the application data structure. The multiphysics model data structure comprises a representation of models of physical systems. Geometry data representing geometry subroutines and call data representing geometry subroutine calls are added to the embedded multiphysics model data structure. Data representing application features are added to the application data structure. Each application feature comprises one or more of (i) first data representing a form feature, or (ii) second data representing an action feature. A customized application data structure is generated providing a customized modeling of the physical systems using a modeling operation, a geometry of the one or more models of physical systems, an application feature, and a geometry subroutine. The customized application data structure is configured for distribution to end users as an application executed by an application runtime engine.

Abstract: A simulation apparatus for adding extra geometries to a model of a physical system. The apparatus is configured to modify a geometry of a model of a physical system represented in terms of a combined set of equations.

Abstract: Systems and methods for modeling physical systems include displaying geometric representation of a physical system on a physics simulation system. User-selection inputs received indicate, for mesh elements, selections of dependent variable shape function spaces representing dependent variables. Geometry shape function space options for simulating the physical system are determined that are common to mesh elements and include a serendipity shape function space of second order or higher. A determined geometry shape function space option is a subset of a combination of the dependent variable shape function spaces and satisfies accuracy criteria based on an accuracy ordering of shape function spaces. A finite element mesh for the physical system is created based on the mesh elements, a selected geometry shape function space, and the selection of dependent variable shape function spaces. A solution to a finite element simulation of the physical system being modeled is generated and the geometric representation displayed.

Abstract: Systems and methods generate a modified application data structure that provides a customized modeling of physical systems in response to customized user inputs received via application feature(s) for new window form(s). The modified application data structure is generated from guided user inputs received through application builder wizard graphical user interface(s). The systems and methods include embedding a multiphysics model data structure in an initial application data structure and defining new window form(s). Window form data representing the defined new window forms is added to the initial application data structure. User-selectable application feature options are displayed in the application builder wizard graphical user interface(s) and application feature data is added to the initial application data structure to create a modified application data structure. The added application features can include data representing widget(s), form feature(s), and command sequence(s).
