Scope

SINAS IV is a suite of modules that support the process of converting the temperature results that are computed with a lumped parameter thermal solver, like ESATAN or SINDA, to input for a thermo-mechanical or thermo-elastic analysis with MSC.NASTRAN.

The tool is developed to solve the incompatiblity problem between the lumped parameter thermal analysis models and structural finite element models. This incompatibility originates in the difference in methods used in the two domains. On top of that there is the problem of the different mesh densities. SINAS IV solves this problem using a conductive interpolation approach in combination with constraints prescribing the average temperature of the thermal nodes to the finite elements.

The software version available for download (see below) is a windows version and runs on Windows-2000 and Windows-XP. It requires to have both MSC.PATRAN and MSC.NASTRAN runing under windows.
