Problem with negative volume in CFX
 
Guys, I'm trying to run a case in cfx, but the next problem was reported:

* ERROR # 002100012 has occurred in subroutine cVolSec. |
* | Message: |
* | A negative ELEMENT volume Has Been detected. This is a fatal |
* | Error and execution will be terminated. The location of the first |
* | Reported negative volume is below. |
* | Volume:-0.1504E-09 |
* | Location: (0.17198E +02,-0.96809E +00, +01 0.16941E)

how can I solve this problem??

check your det 2x2 or det 3x3 to find the negative cells. i don't know, if you use tets or hexa. if you use a blocking approach, then check your associations (rmb on edge/show association) or use a scan plane.
