Error #004100018
 

hello everyone,

I am working on air and water mixture analysis. but while simulation it is showing me error:

ERROR #004100018 has occurred in subroutine FINMES. |
| Message: |
| Fatal overflow in linear solver





I don't know whats the problem, but while simulation it is showing some notice:



| ****** Notice ****** |
| The Wall Heat Transfer Coefficient written to the results file for |
| phase: air |
| on domain: fluid5 |
| is based on the turbulent wall function coefficient. It is |
| consistent with the Wall Heat Flux, the wall temperature, and the |
| Wall Adjacent Temperature (near-wall temperature). If you would |
| like it to be based on a user-specified bulk temperature instead, |
| please set the expert parameter "tbulk for htc = <value>". |

Is there any relation between this notice and the error??? as i am having the multiphase problem, so i defined the heat transfer for air and water mixture.
I think this notice is because of that only... Do anyone have idea about this?? please help me for that...

Thanks in advance/.....:)

I can't answer this, but if you wish others to help, you should specify at least what software you use.

:p Oooops sorry Rami, I forgot to mention the software...
Anyways i am using CFX 15.0 for the analysis...
