different between anisotropic and ...
 

hi all/
i have a question about different between anisotropic and orthotropic and cyl-orthotropic and if i have a simulation a cone shape axisymmetric i draw a 2d for the top and put axis i simulate a heat trans fear from the flow inside to the solid
i have anisotropic materials how can i define the thermal conductivity?
is it true to choose orthotropic in option of thermal conductivity ?
or should i use UDF ?
or there is another way ?
please help
