Hi,

I'm creating  a plate with a hole and using symmetry to analyse 1/4 of the model.

 

So far my mesh looks like this however the mesh needs to have one element in each geometrical area, the coordinates of my points are:

(0,0)

(0,21)

(0.30)

(100,30)

(100,0)

(21,0)

radius of arc: 21mm

I will need to increase the mesh density by doubling it which will give a total of 12, 48 and 192 however I am not sure how to set these precise mesh densities and would appreciate the help.

Thank you, 

DVSH.
