Hi all,

I'm working with a simulation of a wind farm including some wind turbines using the actuator disk model on OF 4.0.

The problem is, as I'm working with a real terrain on a STL file, in order to correctly place the disk I need to know the terrain z coordinate corresponding to a (x,y) location, otherwise the absolute height (terrain height + hub height) would be wrong.

Does anyone have a clue of how to do it?

One way would be to write a code that would read each triangle in the STL and check if the coordinate I have is inside the current triangle, but this doesn't seem to be very effective...

I can't do it manually because this is part of an optimization process, it has to be done automatically.

Kind regards,
Luis
