To mimic spherical nanoindentation on hydrogel a spherical rigid body has been created followed by a poro-elastic box to represent hydrogel.
I would like to study the effect on the hydrogel as the indenter pushes it in.
Hence, I grouped all the nodes on the top surface of a hemisphere and then gave them a nodal force along z-axis to push into the box. However, no matter how great force I gave, nothing happened. I gave -1,000,000 on the load curve to push in but no result.
Could you be kind to tell me what I have done wrong?
I have attached the file.
Thanks.
