Solver Development.
Tailored standalone and integrated solvers for precision and flexibility
Standalone structural solvers
Built on top of Nastran (NASA Structural Analysis), our standalone structural solvers enhance the performance of existing features and introduce new, advanced capabilities.
- Our Structural Analysis Toolkit (SATK) solver reads the normal modes calculated by Nastran’s SOL103 analysis and performs random vibration response calculations more efficiently than traditional Nastran methods.
- Advanced functionalities for calculating peak responses in addition to RMS response deliver a deeper understanding of complex structural behavior.
- The solver reads Nastran results and generates detailed reports and new insights, including margin of safety calculations and laminate failure indices.
Integrated structural solvers
Integrated structural solvers for existing finite element platforms, such as Simcenter, enable seamless analysis within established workflows.
- Durability analysis: Specialized solvers capable of conducting stress-life and strain-life assessments, as well as fatigue failure predictions for welded joints using the British Welding Institute (BWI) method.
- Laminate analysis: Integrated solvers use classical laminate theory and account for complex anisotropic behaviors, such as sheared fabrics, in laminate analysis. Plus, optimization solvers based on both gradient-based and stochastic methods optimize laminate layup definitions.
- Correlation analysis: Solvers for efficient mode shape and Frequency Response Function (FRF) correlation calculate metrics such as MAC and cross-orthogonality between simulation result files and test data.
TMG thermal solver
The high-performance TMG thermal solver supports finite volume and finite element formulations on a finite element mesh.
Dedicated modeling features for the space and gas turbine industries highlight TMG’s strength in addressing the unique thermal challenges of these sectors—where precision and performance are paramount, and thermal analysis is a core design driver.
TMG thermal solvers enables you to:
- Model conduction, convection and radiation heat transfer for steady-state and transient analysis
- Streamline model setup and reduce solution time with specialized components for thermal control devices, contact modeling, and multi-layer insulation
TMG’s parallelized solver accommodates nonlinear, anisotropic, and orthotropic material behaviors, along with complex thermo-optical properties.
The TMG thermal solver includes a built-in 1D fluid network solver, and it integrates seamlessly with the TMG-CFD Solver.
TMG-CFD solver
TMG-CFD is a robust and extensible fluid dynamics solver for high-fidelity thermal-fluid simulations in aerospace, electronics, automotive and turbomachinery domains.
A single-phase, fully coupled, pressure-based Navier-Stokes solver, TMG-CFD uses a control-volume finite element formulation (CVFEM).
A Rhie-Chow-type coupling term ensures stable pressure correction on the collocated grid.
The TMG-CFD solver supports a range of RANS turbulence models—solved decoupled from mass-momentum—alongside the energy equation.
It also handles humidity, mixtures, passive scalars, and particle tracking, enabling its application to diverse engineering problems.
Support for periodic and cyclic boundary conditions, rotating frames of reference, and simplified models for fans, pumps, screens, and blockages provides a versatile modeling toolkit.
TMG-CFD is fully parallelized and integrated into Maya HTT’s co-simulation framework, enabling coupling with TMG for conjugate heat transfer calculations.
Thermal solver
The Thermal Solver, a voxel-based, steady-state and transient conduction solver, delivers ultra-fast performance by leveraging NVIDIA GPUs.
Designed for non-expert analysts, the Thermal Solver voxelizes the computational domain directly from CAD geometry with an automatic algorithm that refines discretization around key geometric features.
Originally developed for plastic injection mold cooling analysis, the Thermal Solver supports 1D fluid-network cooling channels, plastic freeze time prediction, and dedicated models for baffles, runners, and heaters.
Recent enhancements include a channel design algorithm that uses an adjoint solution to optimize cooling channel placement. The Themal Solver is the numerical engine behind Maya HTT’s Simform Mold Cooling Analysis platform.
TMG Correlation
TMG Correlation is an add-on to TMG that enables engineers to calibrate thermal models against test or reference data with high accuracy and speed.
It uses an adjoint-based solver to compute gradients for hundreds of design variables in a single run, dramatically reducing correlation time from months to days.
The tool supports both steady-state and transient problems, automates the optimization process, and requires no user coding.
TMG Correlation can also be used to calibrate a reduced thermal model to a validated detailed model, bringing down the calibration time needed from weeks or months to hours.
It’s especially valuable for industries with strict certification standards, such as aerospace, where it helps validate digital twins and streamline thermal verification workflows.
