I am currently working on implementing a strain energy density function that requires the use of the left Cauchy-Green deformation tensor, B
Looking in the documentation for nonlinear hyperelastic structural materials, I see this is not a built-in/provided quantity in COMSOL. I'm currently working on using the same mathematical workflow used to calculate C to calculate B for the strain energy density function, but was wondering if anyone else has done this, had any tips, etc.
Thanks in advance

Hi Eric,
