Hello,
I am trying to run the tutorial "Bump in a channel" but changing the geometry. I would like to change the smooth bump into a half circle.
Unfortunately, I always get this error at the first iteration when running SU2

CSysSolve::modGramSchmidt: w[i+1] = NaN
terminate called after throwing an instance of 'int'

I use gmsh for creating the geometry and the mesh, I enclose the gmsh file (replace .txt by .geo). The configuration file is the one of the first tutorial "Bump in a channel".

Thanks for your help.
Laurent.
