Wrong Material Orientation ?

Hello community,

 

I'm trying to create a uniform Material Orientation on the whole Model (CFRP Rim). Unfortunatelly I always get weird orientations on the transitions of the rim ( as you can see in the picture). Is there a possibility to make them all pointing in one direction ? Otherwise the plies also have wrong orientation.

Edit: I already tried to define it by vector and by the generated coordinate system but it doesen't change.

 

Regards,

Pawel

    I've found the material orientation functionality to be pretty robust. A few comments.

    You may want to consider turning on the visibility of the systems you are referencing to better understand the orientations that are being applied. Can you upload a screenshot with the reference system visibility on so we can see it.

    There are several (better?) tools available for working with systems and assignments such as Orientation Review, Quick Coord Creation, and the Material Orientation Tool in the Aerospace menu.

    You may have some elements oriented such that their normal is parallel to the system axis so it is unclear which direction should be projected? Also, possible that your system is cylindrical?

    FWIW

    Thank you Todd for your reply.

     

    Yes, my system is cylindrical, it is a Rim as you can see in the below picture. I tried the orientation with a cylindrical coordinate system and with a rectangular one but i get in both cases arrows pointing not just in one direction. Is there any possibility to acomplish that ?
