      What values are to be put in Ogden 2nd order input - D1 and D2?n

      In general, one needs to have incompressibility information (derived from volumetric test data), for the Ogden model. For a perfectly incompressible material, it's advisable to leave D1 and D2 as zero. Otherwise, with the initial bulk modulus (K0) known one can put D1 = 2/K0 and set D2=0.n
