Re: how do increase mesh size
Right click Mesh and choose Create mesh. Then use the Mesh Density slider to set the size that you want (moving the slider to the right increases mesh size and moving to the left decreases it).
You can also type your own values by choosing option Mesh parameters (below mentioned slider).

Re: how do increase mesh size
Agreed. In addition, optimizing mesh size to be increasingly dense in high stress areas can be achieved by using h-adaptive option of study properties. check the box "coarsen mesh...." so lower stress areas are more roughly approximated.
