Meshing error
 

Hello guys im new in ANSYS and i have a final year project on wind turbines blades. I followed some tutorials and i managed to solve one airfoil the NACA 0024. I have told to test few more airfoils but i got an error about the mesh quality and topology for the airfoil GOE244. I am using the Ansys modeler to mesh the airfoils and i have been told to try the ICEM but i am short of time and i am struggling with it. So i am wondering if someone has any idea how to do it.

Thanks
