Orthotropic material - 'element' or 'material' axis?

[picirrottola]

Hi to everybody.

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.

Many thanks

Hi Piero,

The X, Y, and Z material properties are based on the global coordinates and you cannot define local material properties.

This would be an excellent comment to add to the idea station.
