Cannot solve a simple 3D transient model

[lcheng9]

Hi,

The attached project files are trying to solve a transient 3D cylinder model, the geometry is shown below. While the solver returns the error about the NaN value. Could you please guide me how to resolve this NaN value issue? Thank you.

Error in "void CSolver::SetResidual_RMS(const CGeometry*, const CConfig*)":
-------------------------------------------------------------------------
SU2 has diverged (NaN detected).
------------------------------ Error Exit -------------------------------

To run this model, please remove the ".txt" suffix after downloading these two files.
