Hi,

I'm trying to run a su2 simulation for a simple structured mesh (cube with a cylindrical hole inside).
However, while running, it stops after reading all the boundary elements (corresponding to the physical surfaces of the mesh).

Can someone help me with this issue?

N.B. I'm using the following configuration file:

Hi, you assigned to Inlet surface three different boundary conditions.
I suppose your cfg file should be
MARKER_EULER= ( Top, Bottom, Inside )

%

% Marker of the far field (0 implies no marker)

MARKER_FAR= ( Inlet, Outlet )

%

% Marker of symmetry boundary (0 implies no marker)

MARKER_SYM= ( Sides)
