3D Solid Material oriantation for MAT9ORT

Hi Everyone,

I started playing with MAT9ORT cards to gain an ansight on how to work with this material type. However for this, I'll need to assign a normal direction to my solid, but I am struggling to do so. I am using Analysis -> System -> Material orientation and try to align it with a vector / y-axis, but it does not work. It just shows like this:

Please refer to the picture for details.

How would I prepare my solid for a MAT9ORT use?

Best Regards,

Lennart

Please try in the Aerospace-OptiStruct user profile menu, click Aerospace > Composites > Material Orientation to bring up the Material Orientation dialog box.

Hi Rahul,

this unfortunately did not help it. I am using this dialog box to create a material orientation, but when I click apply nothing happens.

EDIT:

I select all Elements.

I use orientationmethod by curve

I choose a line

I click apply

and chaos ensues, just like before.

EDIT2:

I have created a coordinate system uznnd tried to reference the vector using its 2-axis (y) an it just creates the same mess, although i looks differently.

Okay, so this is starting to get more and more complex. I remeshed to have perfectly cubic elements, but appearently they also seem to have an induced chaotic material orientation.

Please make sure to use latest version of Hypermesh desktop 2017.3.Material Orientation for Solid elements supported in 2017.1 version. PFAscreenshot from help.

Dear Rahul,

thank you for your fast answer. I am using HyperWorks 2017.2, so this cannot be the issue...

Best Regards,

Lennart

EDIT:

I appended the HyperWorks-Model, perhaps you could have a look yourself?

Okay, it kind of got solved.

For everyone who has thr same issue.

The System or the Mateial orientation dialog does NOT work for this. (2017.2)

However you can create a coordinate system und put it into the property as CORDM. Select 'USER' and choose the coordinate system. The materila will orient itself around the X-axis.

Thanks for the update.

Hi Turbokraken,

which is the procedure you used to create your coordinate system?

FYI

Ply orientation support for PCOMPLS property is available from HperMesh-OptiStruct 2019.Orientation issue is fixed for MAT9ORT for solid elements.

Thank you Rahul!

Just checking in a few years later. Using HM 2024.1. There still does not appear to be a way to change the node order to apply a n1, n2, n3 coordinate system. Has anyone found a way?
