how do i know ICONV is either 1 or 2 ?

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 ?

IF (ICONV.EQ.1) THEN ... ELSE IF (ICONV.EQ.2) THEN ... END IF

Thanks for repl. however, i know IF statement below. what i want to know is when ICONV is either 1 or 2.

IF (ICONV.EQ.1) THEN ... ELSE IF (ICONV.EQ.2) THEN ... END IF

I don't think you need to know exactly when STAR calls COTEET or why, it is enough to know that ICONV=1 means you need to return the H for the given T, and ICONV=2 means T for the given H.

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.

Hi Richard.

thank you for your opinion. let me try to find out what factor makes ICONV be either 1 or 2.

Best Regard.
