Mesh did not appear when number of nodes were specified along a curve
 

Hi,
I am meshing a blade with unstructured grids. As we all know, the trailing edge issues can be solved by using thin-cuts. I did this with an edge criterion of 0.2. However, i left the the number of the nodes on the trailing edge line blank. the mesh comes out nice but the trailing edge was a little coarse. When I specified the number of nodes on the trailing edge line and remeshed, the mesh of the blade did not appear. Is there a way around this?
