[EnergyPlus_Support] Performance Table for Biquadratic Curve

Hi,
i would like to create a biquadratic curve thanks to datas extracted from the literature. I used a Performance Table Object with two independent variables. I looked at the example file LookUp Tables and have done something similar.

My problem is that the simulation crashes when i add this object into my idf file. The example idf file doesn't crash.
I have tried to change the interpolation method without any success.
I gave 6 * 6 data pairs.
Units for X and Y are temperature.
Unit for Output is dimensionless.
I put temperature in Celsius but i put only positive temperatures.
Is it necessary to put Kelvin temperatures??


I hope that someone could help me.

Many thanks.

Jerome DEROCHE
