T-RIX Calculation Service
=========================

CalcTRIXService gives access to the TRIX calculation.
It only contains two function, ``CalcTRIXService.GetTRIXCalc`` for getting a ZVI calculations and
``CalcTRIXService.SetTRIXCalc`` for passing it back to windPRO.
The calculation is very simple.
You need at least one WTG obejct, one meteo object, and elevation data that is used as TIN for the calcualtion.
For changing the underlying elevation data used in the calculation, change the dataset that is used as TIN.
