Hello, 

I am attempting to mesh a hollow shaft with a transverse hole. The model has been split into 1/8 of the original model. See picture. I am wondering what is the best method for modelling something like this. The shaft is under a 10kN tension force.

This is sweepable geometry. You can confirm that by right mouse click on mesh and select Show Sweepable Bodies.

Apply a Method to to solid and set it to Sweep.  On the Details window, select a Source Face, which is the outside face. You can select how many elements through the wall thickness.

Then right mouse click on the Sweep and select Inflate this method.  Pick the circular edge of the transverse hole. That will put smaller elements around the hole.

Hello,

Thanks for you're reply. When i try to inflate I'm getting the error (The meshing failed due to quality checks.  The mesh does not meet the specified Shape Checking constraints specified.  Please look at the mesh quality and adjust meshing options or mesh sizes to obtain a better quality mesh, or relax the shape checks.)

I'm guessing that you have the same project as this member?

Try reducing the default element size in the Mesh Details window.

How does the mesh look if you suppress the inflation?

[cahillr8]

Yes the same project. Reduced the element size but still getting the same error. The mesh below is the mesh generated from the sweep method.

The element size is still too large and the number of division on the sweep is too large.
