So I have been delving into composite analysis and have to do analysis on an aluminum honeycomb core, aluminum skin composite. The honeycomb has orthotropic material properties and I know what they are. It allows me to enter all the data, save and apply it to my composite shell; but when I go to run the analysis it gives an error that the "Othotropic properties are not proper (see output file)". I do not know what would cause this or where to find this output file as well. The skin is an Isotropic material, I don't think that would affect it but I don't really know what SW's capabilities are. Please if you have anything that could help me that would be awesome, all suggestions are welcome.
