Hi Justin, I haven't looked at your new example but what you are trying to do involves non-standard "mixed boundaries" since a given boundary is sometimes a physical boundary and sometimes an interpolation boundary. The general way to handle this is with the "mixed boundary" option in ogen -- see sampleGrids/backStep.cmd for an example and the ogen documentation. I suggest that you practice first in two dimensions. Regards, Bill On 05/01/2013 10:07 AM, zmh021810 wrote:
Dear Bill, Last time you told me about the pipe connection problem and asked me to change the grid order in Ogen file, I did it and it was OK. Now I want the generate the same thing. the only different thing is the location of the branch pipe's position. Now it is in the bottom. However, I can not generate good grids. I change the order again but it is still not good. Hope you can have a look about it if you have time. channel.cmdx is the Ogen file gh.cmdx is the Cgins file. Best wishes for you! Justin
