The low mach number approximation in fluent

Dear all,
I just want to clarify whether the low-mach number approximation is used in Fluent. Could not find any info about this in fluent manual. I am simulating fires, and wonder whether compressible or imcompressible NS should be solved. Cheers Jamie |

It is not in Fluent . But I have made my UDF to simulate it. contact me at my email id

Thanks for your reply. The email I sent you bounced back.
From my understanding, the LMN approximation is used to filter out the acoustic waves, i.e. a backgound pressure is used to replace the actual pressure. Correct me if I am wrong. So, in fluent if no LMN approximation is used, equation containing the actual pressure is soloved? Is the main purpose of this approximation just to simplify the equation for easy solution? Did you mean that you have used the UDF to include the LMN in fluent? If so, could you please also explain this in more details. Your help is very much appreciated, Jamie |

one friend suggested me to ask u about my prblm i am doing on mixed flow compressor,having speed 40000,and pressure ratio of 4,i tried to use coupled implicit solver,but getting lot of errors initeratons, may i use segregated solver for this high speeds also,
pls help me in this |
