Dear nek5000 users, Recently I have defined a cylinder geometry, with boxes at the centre, curved elements at the side. However, the connection of elements at the transition is not perfect, in the attachment. Will the resolution be fine? Is there any better way to solve this problem? It seems I need to draw my own grid through prenek. Thank you. Regards, Simon
Hi Simon, I'm not certain of the origins of your mesh, but the resolution would be to define a 6x6 box for the interior, instead of 8x8. That part can be done with genbox. hth, Paul ________________________________ From: [email protected] [[email protected]] on behalf of [email protected] [[email protected]] Sent: Wednesday, March 25, 2015 12:25 PM To: nek5000-users Subject: [Nek5000-users] Cartesian-to-cylindrical mesh resolution Dear nek5000 users, Recently I have defined a cylinder geometry, with boxes at the centre, curved elements at the side.

Dear Paul, Yes, that's what I did. But I got another error message, which I don't know how to solve. Do you have any idea? 2773 2 4 Matrix: SELF!! 1 SELF!! 1189 1377 1189 1377 2 SELF!! 1360 1206 1360 1206 cont: SELF!! 2773 ??

Dear nek5000 users,
Recently I have defined a cylinder geometry, with boxes at the centre, curved elements at the side. However, the connection of elements at the transition is not perfect, in the attachment.
Will the resolution be fine? Is there any better way to solve this problem? It seems I need to draw my own grid through prenek.
Thank you.
