Hello everyone,

Initial Situation:

I have an issue regarding defining an appropriate coordinate system and stacking direction for my model.

Below is an image illustrating the issue. In Case 1, I was able to define a cylindrical datum coordinate system for ring-shaped cells where:

• 1 in the radial direction
• 2 in the tangential direction
• 3 along the cell's axis of rotation
• The stacking direction aligned with the 3rd direction

Problem:

Now I need to adjust my datum axes so that:

• 1. along the cell’s axis of rotation
• 2. in the tangential direction (unchanged)
• 3. in the radial direction
• The stacking direction still aligns with the 3rd direction

I tried to achieve this by applying an additional rotation of -90° to the 2nd axis, but my model and the routine I received do not allow this. Please, I am looking for a method to define a suitable datum axis for the Case 2 in the picture.

Thank you in advance for your help

Best regards

Arold
