Hi all,

I am having trouble tracking down a reference for how to enter a matrix into the "Elasticity matrix" text field for a material I am defining. Can anyone tell me what the correct syntax is?

Thanks,

Matt

I figured it out. It looks like the elasticity matrix needs to be entered as a comma deliminated vector.

I didn't see that anywhere in the reference and only found it through trial and error.
