I have a geometry with 5 (and more) anisotropic bodies. Currently I am manually writing their elasticity matrix, by selecting D = User Defined and then entering 21 data entries in the elasticity matrix. Repeating this five times for five different bodies.
This become quite hectic when I have 10 and more anisotropic bodies.
How do I add it automatically (D = From Materials), using a .csv or .mat or .txt file.
DVoij where ij = 11, 12, 22, 13, 23, 33, 14, 24, 34, 44, 15, 25, 35, 35, 55, 16, 26, 36, 46, 56, 66 ij = ji
Kindly help.

Hi,
to my knowledge there is no precooked option to do that. But you can set up a model method in Java Code. It will start with something like:
model.component("comp1").material("mat1").propertyGroup().create("Anisotropic", "Anisotropic");
Check the COMSOL Programming Reference Model. It will require some time and focus to get it to run, but the methods are very powerful and it is worthwhile to learn it.

Is it really 5 different anisotropic materials, or just 5 orientations of the same material? In the latter case you can use one material, and just assign different coordinate systems to each domain.
