Intradiscal pressure in ABAQUS 1

[AminKB]

Hi,

I'm modelling and intact spinal segment under pure axial compression. In order to indirectly validate with results from literature I need to find the intradiscal pressure (hydrostatic pressure of the nucleus as I understand). The nucleus is defined as an incompressible isotropic hyperelastic material with hybrid formulation elements.
Can someone please tell me how to find this?
Is the PRESS output the I'm looking for?

Many thanks
Amin

I wasn't a 100% sure Press and hydrostatic pressure are the same. This helps a lot. Thanks a lot.
