Assigning material orientation does not work

Hi there,

I am trying to assign a proper material orientation to my mesh, but it fails. I just created a really simple example following some YouTube tutorials.
What I do is: I create a simple surface and create a local coordinate system, then assign the material orientation by system ID. You can see what it does if I do so below.

Is there any way around this? I am using Abaqus as a solver (don't know if thats relevant here).

Thanks alot for any advice!

just to make sure of your steps, did you do exactly:

- select elements

- select system

- click assign

correct?

Have you tried the other options such as system axis?

I'm not quite familiar to Abaqus for Composites. Not sure if you assign the orientation to the elements or to your sections.

Yes I did exactly as you mentioned. Still does not work. I also tried out all the other options as system axis etc.

Hi Cluue,

For Abaqus Solver, easiest way to apply composite orientation is to assign it to the property, not directly to the element.

Please follow these steps:

1 - Create a system in the 0° direction of your composite

2 - Make this system an Orientation system

Select Card edit function and select the system

Once the system has been selected, check the Orientation box, and give a name to the Orientation

Then check the loacl_dir box and modify locdir value : write 3 to indicates that the O° is your x axis (read Abaqus Solver help for more details on that)

3 - Assign the orientation to the property:

Select the property in the model Browser and in the entity editor, check the Orientation box:

Then select your system.

4 - You can now review the orientation of the element where this property is assigned

Hope this will help you.

Regards

In addition to my previous answer, if you use the Composite function (in 2D panel), you just need to create a system.

This option will transform your system in Orientation, add locdir value and assign this orientation to your property

Do you have a link to the right part of the abaqus solver help where i can find more details on locdir? As far as I can tell right now it seems like 1 is always the x axis or am I wrong? Currently trying to make that work for an cylindrical and spherical coordinate system. Anyways your advice already helped alout!

So here is what I'm dealing with. I created a orientation coordinate system which is spherical and which is located right in the middle of my spherical shaped mesh.

no matter what locdir I am entering it does not change the outcome of my ply.

Do you know what I am still doing wrong here?
