Default cylindrical
Posts: n/a
Hello everybody! I am writing a code for 3D air-flow in a cylinder.The problem that I am facing is how to treat the special characteristic of the cylinder,where at zero and at 360 degrees the grid coincides.Any suggestions?

The code is with finite volumes and collocated.The circumferential direction is the I. At I=1 and I=NI, the cell size is the same as NI-1 and 2 respectively.

Should my solver (TDMA) have any change from the cartesian version?

Thank you
