How to get nodes coordinates for a certain cell ?
 
Hi !

While looping over cells in a thread I need to define coordinates of all cell nodes to provide the next calculations. Wouldn't you give me some information about this matter ? I suspect that the functions I need are NODE_X(node), NODE_Y(node), NODE_Z(node), but how can I define this "node" parameter ?

Best wishes. Mikhail

Re: How to get nodes coordinates for a certain cel
 
I am also trying to get the nodes coordinates. At the moment, I am using the follow expression:

xc1 = NODE_X(C_NODE(cell, thread, n));

n is the number of node (0 - 4) for quadri cells!

This expression run well when insert in the main loop of the FLUENT code. But I am not getting to do a loop over the cells nodes in the domain. I contacted the Technical support by FLUENT for to resolve this...

We can to change more informations...

Hi, You can use T-grid to find out nodes coordinates. Under the Modify Boundary panel, select nodes by mouse and press Centroid button, you can easily get the coordinates of the nodes. Bye
