Hello, all
I am a biginner user of Fluent, now i encounter two confusing poblems. 1) what the meaning of the following message: Error: fluent.6.1.18 received a fatal signal (SEGMENTATION VIOLATION). Error Object: #f 2) can we use several DEFINE_PROFLE macros during one computation? 3) how can we simulate dy/dx using UDF, where y is the mass fraction? thank u very much in deed. Merry Christmas.

1) You usually obtain a segmentation violation error when you try to do invalid operations, such a division by zero.
2) You can use all DEFINE_PROFILE you need in your UDF, but you can hook a single DEFINE_PROFILE function to each boundary condition. 3) What do you mean? What's your goal? Hi ap |

Mr/ Madam AP.
Thanks a lot for your reply. I want to compute a chemical concentrabution distribution in a micro channel. And there are two differnt boundary conditions in this domain, which are mean cell seretion and comsumption. Therefore, i have to simulate Two different dC/dn in one computing domain using Fluent, (where C is the concentritiona, n is the nomal vectors of the top wall and bottom wall. And C can easily transformed into mass fraction. ) i am not sure if this problem can be solved by Fluent, and there are no such examples provided by Fluent Tutorial Guide. Thank you verymuch indeed. Sincerely Steven |
