orthotropic please help
 

can any one help me
i simulate heat transfer in nozzle with k epsilon
i use an anisotropic materials in the solid of nozzle
i put a thermal conductivity in an orthotropic
after i finish my iteration how i check a thermal conductivity in the solid parts and i found it 0
how it happened ?
and how can i be sure if my simulation true ?
and what is the best skewness of 2d mesh ?
please answer ?
