MAYA Heat Transfer Technologies Limited NX I-deas TMG Radiation

Description
NX I-deas TMG Radiation is an add-on module to either NX I-deas TMG Thermal or NX I-deas ESC. It provides additional advanced modeling and solver options for the most complex radiation heat transfer simulations. NX I-deas TMG Radiation offers capabilities for modeling a wide range of radiative effects, including multiple enclosures, specular and transmissive surfaces, solar or high-temperature sources, orbital heating, articulating systems, temperature-dependen t emissivity, bi-variable tables, thin and thick optical lenses, ray extinction in solids, thermal scattering and many more. NX I-deas TMG Radiation heat transfer technology highlights View factors can be computed using a hemicube algorithm, leveraging an OpenGL rendering-based scheme which delivers unmatched performance for large models View factors can also be calculated using standard analytical techniques: Contour integral technique for unobstructed views Nusselt sphere method with adaptive subdivision for shadowed elements The effects of specular reflections and transmissions in a radiative exchange problem are computed using an advanced ray-tracing procedure that adjusts the view factor matrix in a two-pass method Surface geometry for radiation models is defined using shell elements or solid elements free faces created directly on part surfaces. For accurate modeling of focusing effects, curved surface elements can be used. Rays are launched between elements based on the view factors, and they are traced through the enclosure until they are extinguished Angle-dependent properties and refraction are also supported TMG solver features: A radiosity approach (Oppenheim's Method) to construct the radiative exchange matrix; an advanced sparse matrix solver is used to solve the equations, providing very fast performance for even the largest models A matrix inversion solution based on Gebhardt's Method is also available for calculation of direct radiative terms A stochastic (Monte Carlo) approach is also available
