Dear Stephen,

I have reproduced the simulations of Silker et al (1988) and Prendergast
et al. (1996) using ABAQUS. It seems ABAQUS works well on soft tissues.
You can find these results in our recent paper "Evaluation of finite
element software Abaqus for biomechanical modelling of biphasic tisses,
by JZ Wu, W Herzog, and M Epstein" (J Biomech, in press, will appear
in April or May 1998)

Regards, John Z Wu
