The geometric model of the breast is as shown in the figure below. There are skin, fat, tissue and tumor. The shape has been simplified but it is close to reality!

And each part has its own material properties, I use hyperelastic mooney-rivilin model, the values are as shown in the picture below.

The geometric model and material properties should be close to the real situation, there are other reasons why gravity didn't affect the deformation?


My breast model is reconstructed from the MRI image. The gravity of the breast MRI is towards the -y axis. How can I use ansys to eliminate the influence of this gravity? Can I directly set a gravity in the direction of the +y axis? Will it work? (It doesn't matter if the geometric model does not consider the upper and lower versions when eliminating the gravity of the -y axis)

Thanks for your help!
