Orthotropic orientation
Hi,
I am using the propertie /PROP/TYPE6 (SOL_ORTH) for an orthotropic material.
When I now set my skew_ID and Psi to 0 and Ip to 3, would the direction 1 have the same orientaion as the x-axsis of my global coordinate system?
And would the orientation of the direction 1 be the same as the x-axis of an local coordinate system when I choose a value of 0 for Ip and Psi and the skew_ID accourding to the local system?

what is the solid formulation and Iframe value used?
if the Isolid is set to 1, 2, 12, 17 and Iframe set to 0, 1 then RADIOSS assumes global system and ignores the element system if Iframe is set to 2 element system is used.

I think it answers my question, thanks!
Isolid was set to 14 and Ismstr to 2.Though my model explodes now.
I will upload it... again...0 -
I am using a solid element, so Isolid 1, 2, 12 and 17 are not compatible?

Element formulation may depend on the material law. but in general if you are using 1, 2, 12, 17 with iframe set to 0, 1 then global system is assumed.

A nother thought came to my mind, is there a way to review the orientation?

you can use the below script to check the element orientation.
go to http://www.altairhyperworks.com/Script-Exchange.aspx and search for the script number.

Hi,
I have a similar query regarding orientation of orthotropic property /PROP/TYPE9 (SH_ORTH). There is an option to orient the property by reference vector. That is fine for flat surfaces, but how it works for more complex curved surfaces like spheres?
