Hi,
I encountered an error message while i was solving using cfx-solver. i think it might be due to the mesh. Is there any reason for a mesh to becomes negative volume? I am modelling a cylinder,and what i am thinking is it may be caused by the higher length scale used.Any such problems before? I had copy the error message below. Thanks, Maga | ERROR #002100011 has occurred in subroutine cVolSec. | | Message: | | A negative SECTOR volume has been detected. Execution will proceed | | but this is a possible cause of robustness problems. | | The location of the first negative volume is reported below. | | Volume : -0.2421E-14 | | Location : ( -0.99474E-02, 0.28970E+00, -0.39715E+00) | | This warning may be made fatal by setting the expert parameter | | 'negative volume option = 1'. |

You have to debug the mesh motion and find why it is folding the mesh. Do a simulation where you write out the mesh every timestep for a few timesteps before it crashes and you should see where it folds.
Once you have found the location then you need to fix it, but I will wait for your return posting before we go there. |
