I am trying to use EBSILON to simulate the CSP power plant with a solar tower, I want to optimize the layout of the heliostat field, I have searched the internet, but i can’t find any free software, is there anyone know about this?
May I ask exactly what you mean by "optimise the layout"? With respect to what variable? Overall field area (look for a minimum of area) or if the area is fixed maximise the radiation flux on the tower overall, or at a particular time of day? Please be clear in your mind exactly what you are trying to do - it will save you a LOT of time investigating the effect of a numerous different variables.
