Because I have to use an emispherical and thin solid dome, immersed in a fluid domain, and it is made by conductive plastic material (it is obviously orthotropic), I didn't found, reading documentation, any indication about how to build a 'Local Coordinate System'
So, I should like to know if X Y and Z axis (indicated in Material Database panel) are global or local.
If they are global, this is a serious limit to this very fine software; if not, I really will appreciate any help to resolve this issue.
We need to create 3 versions of an orthotropic material in the custom CFD library, in order to be able to have the correct properties per the installation. Examples of orthotropic materials I am using are PCBs (Printed Circuit Boards) and graphite thermal interface materials. On both the thermal conductivity of the materials differ greatly in between X and Y vs. Z axis.
All I want to say is that this is time consuming and prone to errors on using the materials and also on updating properties.
