Hello everyone,

I am working on thermal management of electrical machines. I need to use material with different thermal conductivity to represent the machine winding and somehow we find a way to define such material using following code in command editor of material.

   THERMAL CONDUCTIVITY: 

    Option = Orthotropic Cartesian Components

    Thermal Conductivity X Component = 0.87 [W m^-1 K^-1]

    Thermal Conductivity Y Component = 0.87 [W m^-1 K^-1]

    Thermal Conductivity Z Component = 265.0 [W m^-1 K^-1]

The defined material works fine in single region. However, when two regions are set to be anisotropic material and they are using differnt coordinates, the heat transfer between between two regions does not seem normal.

I have tried changing the discernible fraction, edge scale factor and face intersection depth factor in mesh connection of interface setting.

Does anyone know how to deal with it? Thanks.

Sorry for creating multiple posts, I was trying to delete one of them, but I do not know how.
