    "High Mach Number Flow Exists"--Problem with flow simulation/ cylinder local rotation at high RPM

    Asif Nafi

      Experiment Name : Flow over a wing with leading-edge rotation.

      Analysis Type- External Flow analysis(Time Dependent Analysis)

      Airfoil- NACA0024 (0.2m chord,0.6m span),

      Leading-Edge Cylinder- 25mm dia,rotating at 400rad/s , 3820RPM clockwise.

      freestream Velocity-5m/s

      AOA-5 degree

       

      When i started the simulation mesh generation finished properly no prb faced.

      But after some iterations "High Mach Number Flow Exists" was shown in solver..ALSO the PRESSURE n VELOCITY plot was totally green no changes there..

      I have attached the main files. Plz take a look.
