Simulation Modeling Suite
Simmetrix Simulation Modeling Suite™ is a suite of component technology modules to support geometry-based simulation modeling. The Simulation Modeling Suite includes a comprehensive range of functional modules providing a foundation for your simulation application, including: analysis attribute management, automatic mesh generation, export of run-ready data, and results management. These functional modules can be used either independently or in combination to achieve synergy.
The Simulation Modeling Suite uses a unique architecture providing CAD-independent direct access to design geometry without translation. Simulation attributes and queries are performed on a unified topology simulation model, and all necessary queries to the underlying design geometry are managed by the GeomSim interface. The Simulation Modeling Suites enables you to build robust simulation modeling and simulation-based design applications.
Libraries available include:
MeshSim™ Core
Provides for fully automatic mesh generation of surface and solid models. All MeshSim modules support non-manifold geometric models and maintain the relationship between the generated mesh and the original geometry. Offers triangular, quadrilateral, and mixed meshes of surfaces along with tetrahedral meshing of solids, and supports curved meshing of higher order elements and face matching for periodic and contact boundary conditions. Meshing is automatic with no user interaction needed. MeshSim Core also provides extensive mesh sizing and gradation control including curvature-based refinement and an extensible toolkit for export of simulation data. Meshes can be exported to a variety of standard formats.
Requirements: GeomSim Core and at least one GeomSim interface module (Int, Krnl, CAD, Discrete).

GeomSim™ Core
Provides direct access to design geometry through a common interface independent of the CAD system or modeling kernel. This unique access to design geometry creates a unified topology model suitable for simulation including sliver suppression, non-manifold assembly modeling, and volume extraction for CFD, EM, and other far field applications. In addition to interfacing with CAD, GeomSim Core allows the importing of geometry primitives (curves, surfaces, BSpline) to create GeomSim geometry. GeomSim Core also provides specification, definition, and assignment of geometry-based attributes related to the simulation problem. A broad range of attribute types and definitions are supported to provide the ability to define a wide range of simulation problems and applications including geometry-based mesh control and associated queries to support automatic meshing through MeshSim or any other mesh generation software.
Requirements: GeomSim interface module (Int, Krnl, CAD, Discrete, Import).
