AS_Aero Senior Member Join Date: Mar 2013 Location: Germany Posts: 357 Rep Power: 14	Hallo All I have an issue with my fan simulation where my simulation blows up due to some negative volume error. In my output file which was generated after 100 iterations where my simulation crashed and there was an error message for negative volume and this is clearly coming from my Axial blade mesh that I did in Turbo grid. My concern how to solve this 1. how to visualize this negative volume in CFD post (the error gives the negative volume location) 2. How to solve this in Turbogrid (al though turbogrid creates the mesh and it doesnt show any negative volume in my mesh analysis.
