Element Orientation

Altair Forum User

Hi Experts,

 

I am just a beginner and faced the below problem.

for one of the metallic part model, I have different element orientations for elements (It is not consistent for elements of same part which modelled by automesh option). If I make them using N1-N2 ,. Though it is a metallic material part, my customer would like to get it consistent.

Is there any way to do this? Finally I need to assign all nodes to a cylindrical coordinate system. Will it create again the problem with element orientation.

 

Please support with your suggestions. I m using 2017.2 version.

 

Thanks and Regards

Nithin

Hi,

 

for material orientation review/edit use 2D>composites>material orientation panel.

 

To assign nodes to a cylindrical coordinate system use analysis>system>assign panel. In the same panel, there is also an option for material orientation.

Hi,

Make sure that your element normals are consistent.

Hi Guys,

 

Thank you for feedback. But unfortunately, this is not what I am looking for.

The material is metallic, not composite.

element normal are in one direction, but the element orientations are not. This is the problem. If I make orientation in one direction, normals getting disturbed.

Hope my problem is clear now.

To adjust orientation, invoke pulldown menu Tools>Orientation Review

In tab Orientation, set Function as Align N1N2 dir

Hi Tinh,

Thank you. I am using that option only.

As I mentioned, when we align the element orientation, the normals getting reversed.
