Hello folks!
I'm currently looking into a flow case where the flow is in two large boxes with a small cylinder connecting them. I figured out that this is a great geometry to do hex meshing, with O-grid in the cylinder. However when I try to create three blocks for each separate part, I run into problem. First I create the block for the cylinder, associate the edges and then do and O-grid split, so far so good. Then I create a block for the first box and associates the edges, ICEM asks me if I want to Merge it which I want to. So now I have two blocks. I then associate the edges to the curves on the large box(see first picture). The problem arises when I add the third block to the other box. ICEM asks me if I want to Merge or Replace the blocks, I press Merge since Replace will remove the other two blocks. Then the vertices of the two big blocks for the two big boxes merge and thus creating something that doesn't look like the original geometry(see second picture). Note that I initialize the 3D blocking by choosing the appropriate surfaces. I must have surely overlooked something very simple but I can't figure it out. Thanks in advance Last edited by Polarbear; April 29, 2014 at 12:06. Reason: Spelling |
