Re: [TRNSYS-users] Parameter like an input



Manuel,
  The only way is to change the source code and move the parameter to an input, then recompiling the Type. The TRNSYS engine reads parameters from the input file at the beginning of the simulation and stores them internally. They are never reread so while you can make a parameter value that is the result of a time dependent equation, only the initial result of that equation at the very start of the simulation will be used for the parameter value.
Best,

Hello,

 

I see in the TRNSys docs that variables used in place of numerical values for parameter can’t be time-dependent quantities. However I use the Tess’ Type661, with parameter that’s depending on the time (# of timestep to hold value).

Is it possible to make this parameter is considered like an input?  I could make several versions of this Type661 and add an equation that chooses the right output depending on the time but it’s not possible because it will make too lots of trnsys modules.

So this solution is not possible right here right now. Is there another solution for me?

 

Thank you in advance for your help.

 

Manu
