Abaqus modelling of a finger (orphan mesh)

Submitted by Slayerz on

Hi all,

 I am working with an orphan mesh of a finger made up of:

1) elastic epidermis layer

2) viscoelastic dermis layer

3) hyperelastic fats layer

4) bone

NLGEOM is turned on.

Tie constraints are used between the layers and the bone 

I wish to make this finger 'touch' a cubic object however the job always fails as it is not able to converge.

Will anyone be able to advise on this matter?
