Re: constant card: how can I do in iisibat?

["Laurent Serres" <laurent.serres@xxxxxxxxxxxxxxx>]

Michael,
OK to do that when you write the deck file. But is it possible to write the same  deck with iisibat ?
It' s easy for the input (the output of "equation" statement is the input of an other unit).
But for parameters? Can I obtain something like:

Parameters 3
1.0   MyPar   2.0
 
Regards 
Laurent

  Laurent,
   
  Equations can be used as parameters. You can also use them as initial value for inputs or derivatives.
  However, you should only use equations that give a constant value to do this, e.g:
   
  Equations 1
  MyPar=1.0
   
  Unit 1 Type xxx
   
  Parameters 3
  1.0   MyPar   2.0
   
  Inputs 2
  1,1 1,2
  0.0 MyPar
   
  Derivatives 2
  10.0 MyPar
   
   
  Please note that If you use equations that vary with time or that include Types outputs as a parameter, the equation will be evaluated only once and you might get unexpected results.

    Michael,
     
    with "constant" statement, if I define a constant, I can use it in parameters of several types.
    Can I do the same thing with "equation" statement?

      Laurent,
       
      The "Equation" statement is more flexible than the "Constants" statement but gives the same result if you restrict the expression to the right of the equal sign to a constant.  
      So you can use the IISiBat "Assembly / Insert New Equation" command to introduce constant expressions in your deck files.
       
      If you really want to use the "Constant" statement, you can add it to the "Simulation cards" edit box in IISiBat Control cards (the place which usually includes the "VERSION 15" line).
       
      Regards,

        Dear TRNSYS users,

        I'm trying to obtain the same result with iisibat that I obtained with CONSTANTS card in TRNSYS. I don't find in the help.
        How can I do?

        Thanks a lot.
        regards.
