Add thermal material properties #435

Closed rainman110 closed 8 years ago

rainman110 commented 8 years ago

In an internal DLR project, we want to compute radar and infrared signatures from aircraft. To do so, we need to add some basic thermal properties of materials, which are:

These should be added to

/cpacs/vehicles/materials/material/

As the diffuse emissivity depends on the spectral wave length it should be stored as an array including wave length and the emmisivity factor.

The specific heat typically depends on the temperature. Therefore, it also needs to be an array including temperature and value.

What unit of measurement should we use for the spectral wavelength? Internally, micrometers are normally used but that might conflict with the SI unit system that is used in CPACS elsewhere.

@DLR-LY what do you think?

DLR-LY commented 8 years ago

I agree that we should consistantly use SI units throughout CPACS. Any exceptions would lead to uncertanties in the interpretation. I'd suggest we keep it clean by sticking to SI units for all values.

Merged into main development branch. Will be available at the next release 2.3.1 at the end of this month.

Perfect, thanks! :smile:
