[TRNSYS-users] Defining a Global Variable in User Created Components

[Jeff Thornton]

Aaron,You could use a COMMON statement in FORTRAN to automatically pass this information to the other components but that does, in some ways, defeat one of the basic ideas of TRNSYS: the ability to remain completely flexible.  You could then only use those components together and never separately.  A better idea would be to define the specific heat parameter in every model, use an equation block to set the specific heat:Equations 1Cp_Fluid=4.182Then in every model that uses the specific heat, simply change the units of the specific heat variable to string and enter the "value" as Cp_Fluid.  Every time you change fluids by updating the equation, the other components are automatically updated.Jeff   Jeff Thornton  President - TESS, LLC   22 North Carroll Street - Suite 370 Madison WI 53703 USA   Phone: 608-274-2577  Fax: 608-278-1475  E-mail: thornton at tess-inc.com  Web: www.tess-inc.com    ----- Original Message -----From: "Aaron J.
