Voigt component order question

[prs513rosewood]

Hello,

I'm currently bridging mgis and an fft-based contact simulation code I'm working on (I think I've got something working), and from a brief discussion I had with @thelfer at the d'Alembert coffee room a few months ago I remember that MFront/MGIS uses a particular Voigt-Mandel component order. I looked through the documentation but could not find mention of this. What is the component order used/expected by MFront?

In my implementation efforts I also noted that behaviour.setParameter exists but could not find a way to get the current value of a material parameter (only the default value). Is there something I missed? Thanks for your help!

Hi @prs513rosewood,

Please have a look at the MFront documentation here: https://thelfer.github.io/tfel/web/tensors.html#vector-notations-for-symmetric-tensors

Best,

Thomas
