hello. Im analizyng a Naca 4415 airfoil. I meshed in ICEM. I run an analisis with a spacing of 0.01 and ran Ok. Then I modified the spacing to 0.008 and when the solver began, its stops inmediatly saying: +--------------------------------------------------------------------+ | ERROR #002100010 has occurred in subroutine cVolSec. | | Message: | | One of the sector volumes of an element is equal to or less than | | zero. It means that there exists an illegal mesh, execution will | | be stopped immediately. | | The element sequential number is: 119 | | The element label is: 119 | | The sector volume is: -0.2842E-13 | | The location (x,y,z): 0.12802E+02-0.38100E+01 0.50000E+00 | +--------------------------------------------------------------------+

It seems that the mesh has a element with a negative volumen. Im doing the 2-D mesh, and the extruding it.

Any suggestions?

Thankss Santiago.

Hi,

Use the mesh validation tools in ICEM to find where the problem lies.

Hi,

The mesh validation tools are under the "edit mesh" tab.
