element deletion

HELLO EVERY ONE,

I am working on distortion problem in milling of large aeronautic parts. I want to implement element deletion method on my model. I check several videos and documents regarding this but it required failure criteria and it applied on whole model but I want to deactivate selected element at every analysis step.

Kindly help me Its an urgent task I need to complete.

Thanks in ADVANCE

Hello All,

I have an 3D orphan mesh (Abaqus)  that I obtained from the Gmsh software. I would like to insert a perfect spherical hole in that mesh.

I selected all the elements inside a sphere and deleted them but i am getting a very coarse surface, look at the figure attached

Is there a way to create a perfect spherical hole in a 3D Abaqus mesh ( I do not have the part geometry)  ?

I thought something like,  smooth the inside of the surface of the mesh deletion, but I donot know how to do that.

Dear all,

Currently I am engaged in solving a geological problem. So we have some soil model in the form of disk, there is a circular hole in the center, which has the initial pressure at the reference time  (a modelling of the soil injection with the polymer compound)

How can I recalculate the normal pressure inside the circular hole of the soil model using the DLOAD subroutine if the neighbouring FEs were failed.
