 March 15, 2012, 11:10 Cylinder Meshing #1 New Member   Join Date: Mar 2012 Posts: 4 Rep Power: 6 I was wondering what the best process for using ICEM would be to mesh a cylinder. I wanted the circular surface to have a mesh that radially grows from the center. I have tried using ANSYS meshing but I could not get the circular surface to complete the radially mesh. I had gotten around this by using a small square in the middle of this surface and divided the rest of the surface into four pieces. I am now trying to find a way to get a purely radially mesh. I am new to ICEM and was just wondering what the process would be to complete this mesh, if possible, in ICEM.

I tried following the tutorial for the 3D pipe, but I end up with just a rectangular mesh inside of my cylinder. I associated the edges of the squares at the end of the block to the circular curve. I have attached the image of the block and geometry curves, as well as the incorrect mesh.

Edge association is not correct. 2. If step 1 is done, use edit edge >>> spline 3. Create four points on each circle and associate vertex to point. To improve quality, create O-block as well.

I suspect you have made a very basic mistake about association. Check attached tin and blk files

I am using KIVA and hence not allowed to use o-grid mesh. Here a picture: I am fairly new to ICEM and really dont understand why it is so hard. When I am doing a partially circle ( i.e. 90 degrees ) the mesh is automatically starting from the edge. Thanks a lot for your help!

Create ogrid first. then merge vertices of inner ogrid.
