The Patran MD Nastran Heat Transfer Preference supports the full range of thermal analysis capabilities available within MD Nastran. These capabilities include:
• conduction in one, two, and three dimensions
• fundamental convection
• one dimensional advection
• radiant exchange with space
• radiant exchange in enclosures
• specified temperatures
• surface and volumetric heat loads
• elements of thermal control systems
• contact conduction
MD Nastran can span the full range of thermal analysis from system-level analysis of global energy balances to the detailed analysis associated with temperature and thermal stress limit levels. Within the integrated Patran-MD Nastran environment, you can simulate linear, nonlinear, steady-state, and transient thermal behavior. You can apply loads and boundary conditions either on the model’s geometry or on its finite element entities. MD Nastran’s sophisticated solution strategy automatically addresses the existence and extent of nonlinear behavior and adjusts the solution process accordingly.
