  • Positive of negative Alpha1 in first order Ogden

    Hi,

    I see in Ogden et al. 2004 that alpha_i X mu_i>0 for Ogden formulations with N=<2. However, I see that this is not implemented in MCalibration. In other words, for 1st order Ogden I can get alpha_1 X mu_1<0. Of course I can myself implement the constraint but can you please advise me with this apparent inconsistency?


    Thank you!
