Hello,

I am trying to modify the AREA calculation implementation in grid_structure.cpp to suit my requirement. The case I am running is a 2D axis symmetric problem. The reason I felt I need to edit the current implementation is because the current implementation is based on area calculation for airfoil sections which have two surfaces. Whereas in my case, I require the area enclosed by the body and the X-axis.

I was using the Airfoil coordinates info stored in,
Xcoord_Airfoil[iVertex]
Ycoord_Airfoil[iVertex]
Zcoord_Airfoil[iVertex]

This worked pretty well for simple cases like circle. But dealing with little complex geometries I realised the grid variation is NOT stored in the order points are located on the connector.

I would like to get the X,Y,Z coordinates in the order they are present on the connector. Or any other way to calculate area for 2D axis symmetric body will also be helpful.

Would be grateful for any help.

Thanks in Advance.

I would make sure you know the way the program that made the mesh exports the points to the su2 mesh file. That should potentially help with keeping track of how the points are stored.
