Error in surface plots

Hi everyone,

We have been using SU2 to carry out the aerodynamic analysis of a UAV. The flow has been carried out at low mach number with the Turkel pre-conditioner over a range of angle of attack. The lift drag and pitching moment coefficients seem to be fine, but when we looked at the pressure distribution on the plane surface we found a very weird distribution in one half of the plane. This was the case for both Paraview and Tecplot as well. I have attached the surface plot along with query. Similar aberration was observed for wall shear stress distribution as well.

I was wondering if someone else came across a similar issue and can share with us how to deal with this. Any help would be appreciated.

Hi Rachit,

Is the surface of the body divided into multiple markers? Is it possible that some part of the surface is not being included in either the MARKER_MONITORING or MARKER_PLOTTING option?
