Re: 2d mesh refinement
I am learning to use Salome and wish to creat a simple 2d mesh that consists of a 1.5m by 0.8m rectanglar face. I have attached a screenshot of what I mean - I wish to use an H-grid to mesh a small 0.08m square at its center, transforming to an O-grid out to a radius of 0.3m from the center (the disk). I am struggling to even set up the geometry such that I can select the relevant parts/edges for setting up meshing hypotheses.
I tried simple drawing the 2d shapes (channel,disk,hGrid) and then creating a face from them - but it cuts out the disk
I tried creating individual faces cut out from each other and grouping them but it doesnt let me do this (from what I have now read "group" allows you to select subshapes of a shape not add non-overlapping shapes together)
I tried grouping the 3 overlapping shapes but that doesnt seem to work either :-S
I am guessing I am going abou tthis the completely wrong way and if anyone could shed some light on how I do this that would be great!
Aaah, I have figured it out. I need to use compound and then partition.
