| ||STEP-TAS Conformance Classes|
STEP-TAS provides a tool-neutral format for storing three different types of data used by space thermal analysis tools. The first is related to a Geometrical Mathematical Model, or GMM, where the space-craft geometry is represented by a bounded face model with minimum topology and material properties. The second is the Thermal Mathematical Model, or TMM, used to represent heat flow within a thermal lumped parameter network model. The third is the capture of results data from analysis, test or the operating flight model, or FM.
Each of these areas can be further sub-divided to reflect the different levels of functionality that individual analysis tools might support. These levels, or conformance classes, provide an easy means of classifying the capabilities of the analysis tools. This makes it easier to see whether all aspects of a model created using a particular analysis tool can be handled correctly by both the conversion tool and the target analysis tool without loss of information during the conversion from the input format to STEP-TAS, the conversion from STEP-TAS to the output format, or both.
