 March 30, 2004, 12:44 how do i know ICONV is either 1 or 2 ? #1 mspark Guest   Posts: n/a Hi ICONV is a conversion parameter: 1 for T->H, 2 for H->T inputting to COTEET. How do i know ICONV is either 1 or 2 ?

But I guess that, for example, boundary conditions are specified as temperatures, but STAR needs H for the enthalpy equation. Hence after boundary conditions are defined there would be calls to COTEET with ICONV=1. On the other hand, properties may be functions of T so STAR will need to convert H to T before calculating properties.
