Dear,
I m beginner with comsol software.
I would like to simulate the behavior of composite material. In this way i would like to use the material carbon epoxy in the library.
But when i want selctionned it in the dialog box (bounderies F8) I can't selectionned it.
Must we defined a special reper?
Thanks in advance for your answer.

Hi
First in 3.5 or 4 ? For both if you have an anisotropic material, you need to tell comol to use the anisotropic approach (full tensor representation) and to usea material with an appropriate tensor notation for the stiffness.
Finally aou ust ensure that your coordinate is oriented correctly, linking the given material tensor coordinate to the domain shape corrdinates. But this is model dependent.
The exact procedure is slightly different in the two version, but the principle and approach is th same, check the doc and the examples

Good luck
