[TRNSYS-users] Piston modelling on Trnsys

[David BRADLEY via TRNSYS-users]

Grégoire,

  I am not aware of any existing models. If the equations that govern 
the piston are simple enough then you can enter them as equations in the 
Simulation Studio project. If they are more complex then you would need 
to write a new TRNSYS Type. If you are using Trnsys18 there is a 
dedicated Fortran compiler (called TypeStudio) built in to TRNSYS. If 
you are using an earlier version of TRNSYS then you will need to obtain 
an external Fortran compiler in order to write the component. A third 
alternative would be to develop the piston model in EES, Excel, or 
Matlab and then use the appropriate TRNSYS Type to communicated between 
Trnsys and the external model.

kind regards,

  David
