As a material is it anisotropic and so this surely will matter in this area? I am a bit of a noob so perhaps I've missed something here...</P> Fri, 27 Jan 2023 01:35:06 GMT https://forums.autodesk.com/t5/fusion-design-validate-document/carbon-fibre-in-simulation/m-p/11709005#M45562 steveVLDE4 2023-01-27T01:35:06Z https://forums.autodesk.com/t5/fusion-design-validate-document/carbon-fibre-in-simulation/m-p/11709883#M45563 <P>Are you doing a non-linear simulation?</P><P>&nbsp;</P><P>Linear elastic static stress analysis is limited to isotropic materials.</P> Fri, 27 Jan 2023 11:50:40 GMT https://forums.autodesk.com/t5/fusion-design-validate-document/carbon-fibre-in-simulation/m-p/11709883#M45563 TheCADWhisperer 2023-01-27T11:50:40Z https://forums.autodesk.com/t5/fusion-design-validate-document/carbon-fibre-in-simulation/m-p/11710009#M45564 <P>ok thanks I'll bear that in mind.
