Unleash the power of Isogeometric Analysis with Coreform

IGA is an advanced simulation method that directly integrates CAD models into the analysis phase, eliminating the need for mesh generation, which is often a source of error and inefficiency in traditional finite element analysis (FEA). IGA allows for the use of exact CAD geometry, reducing or eliminating the need to fit meshes or defeature models, leading to more accurate and efficient simulations. This method requires minimal user input for mesh creation and is available for commercial use in the Coreform Flex Preprocessor and Solver.

Benefits:

• Exact Geometry: Maintains true CAD geometry, avoiding approximations that can skew results.
• Greater Accuracy: Produces more accurate simulations for complex shapes, thin-walled structures, and freeform geometries.
• Faster Time-to-Solution: Reduces the time spent on meshing and geometry correction, speeding up the entire simulation process.

FEA is a foundational simulation method used in engineering to predict how structures and components will respond to external forces, such as stress, heat, and vibration. Based on the same Galerkin methods as FEA, Coreform enhances analysis with its cutting-edge isogeometric approach, allowing you to run simulations directly on fully-featured CAD geometry, ensuring higher accuracy and smoother representations of complex geometries, particularly for industries requiring precise structural analysis, such as defense, nuclear, and aerospace.

Benefits:

• Higher Accuracy for Complex Structures: Traditional FEA faceting meshing is replaced and enhanced by Coreform IGA, which eliminates geometry errors with CAD-exact models that smoothly match real-world shapes, even with coarse element densities.

• Reduced Meshing Errors: Coreform’s approach allows for zero-geometry error that arise from faceted mesh generation, providing a more reliable analysis from start to finish.

• Flexible Boundary Conditions: Enables the easy application of complex boundary conditions and constraints for advanced simulations.

• Eliminates limitations: Coreform eliminates limitations relating to phenomena like thin shell buckling/large deformations, shear locking, sliding contact, crack and fracture propagation discontinuities, and spurious spectral and boundary layer oscillations.

CFD is used to simulate the behavior of fluids—gases and liquids—around and within objects. With Coreform’s unique CAD-integrated approach, engineers can analyze fluid dynamics on geometries that are typically challenging for traditional CFD tools, ensuring more accurate results. This allows an optimized process for analyzing complex fluid flow problems, providing more precise simulations in industries such as aerospace, automotive, marine engineering, and automation industries.

Benefits:

• Hex Meshing: Coreform Cubit offers advanced hex meshing, which improves the quality and accuracy of computational fluid dynamics (CFD) simulations by generating structured, high-quality grids that produce more accurate simulations with lower computational costs.
• Python API and Process Automation: Coreform software has a powerful scripting language and Python API. The automation features allow users to reuse mesh generation processes, significantly reducing repetitive manual tasks and customizing meshing workflows, offering enhanced flexibility for adapting to complex projects.
• Comprehensive toolset for streamlining CAD prep: The Coreform Cubit GUI is intuitive and user-friendly, making it easy for new engineers to learn. The command panel and model-building tools enable users to create and mesh models in just a few minutes.
• Reduction in Meshing Time: Cubit accelerates the overall simulation process by cutting down the time spent on meshing.

Neutronics refers to the simulation of neutron behavior in nuclear systems, such as reactors and other energy applications. Coreform’s neutronics capabilities allow for accurate modeling of neutron transport, absorption, and reaction rates, making it an essential tool in the nuclear energy industry, research, and safety analysis. By integrating neutronics with Coreform’s advanced meshing and analysis tools, engineers can obtain highly detailed and reliable simulations of nuclear systems.

Benefits:

• Accurate Neutron Transport Modeling: Coreform uses DAGMC (Direct Accelerated Geometry Monte Carlo) to provide precise modeling of neutron transport in complex reactor geometries, ensuring better prediction of behavior in nuclear systems.
• Multi-Physics Integration: Neutronics can be coupled with other physics, such as thermal and structural analysis, for full reactor simulations, allowing engineers to analyze the impact of neutron flux on reactor materials and cooling systems.
• Efficiency in Simulation Setup: Coreform’s ability to work with complex geometries without requiring mesh simplification is critical for accurate neutron behavior analysis, as simplifications can lead to incorrect predictions in reactor design.
• Comprehensive Reaction Rate Predictions: Simulates neutron-induced reactions, enabling engineers to predict fuel depletion, radiation damage, and energy generation with greater accuracy.

Coreform offers numerous advantages that set it apart from traditional simulation tools. Below are the key benefits that make Coreform the preferred choice for advanced engineering simulations.

Coreform’s innovative Isogeometric Analysis (IGA) technology enables engineers to use exact CAD geometry in simulations, eliminating the need for geometry simplifications and mesh approximations that can compromise accuracy. With smooth, continuous surfaces powered by U-splines, Coreform ensures that even the most complex geometries are represented with precision, leading to highly accurate simulation results. This precision is especially valuable in fields where even minor deviations in geometry can lead to significant performance differences, such as aerospace or nuclear energy.

Coreform dramatically reduces the time required to move from design to analysis. By accepting CAD models directly, engineers can bypass time-consuming mesh generation and cleanup processes that are necessary in traditional FEA workflows. Coreform’s automated meshing and advanced solver enable faster setup and execution of simulations, which translates to shorter project turnaround times. Engineers can focus more on problem-solving and innovation rather than wrestling with model preparation, making Coreform a valuable tool for accelerating development cycles.

Coreform reduces product development costs by streamlining the engineering workflow and minimizing time spent on model preparation. With fewer steps required for geometry preparation, meshing, and model validation, engineers can iterate faster through design and analysis cycles. The ability to perform linear and nonlinear, static and dynamic, structural and multiphysics analyses enables simultaneous testing and optimization of various design aspects. This enhanced efficiency reduces bottlenecks, accelerates project timelines, and allows teams to deliver higher-quality results, ultimately lowering overall development costs.
