CFX subroutines
 

Dear all

I got a Fortran subroutine from CFX conferenc in Germany. the subroutine called anther subrotine called PT_MASS_SH that to caculate particle mass transfer Sherwood number

CALL PT_MASS_SH (SH,ARG(1,5),ARG(1,1),ARG(1,2))

The point is, I did not find any subrotine called PT_MASS_SH in this Fortran subrotine. This means this subroutine is built in CFX program. Any one know how I can know all built in subroutines to use them such in case.
