Hello Support,

My objective is to find the velocity & pressure distribution in water jacket.

In term of boundary condition

I have inflow mass flux 0.7078 kg/sec & known pressure at inlet is 1 bar.

also I have outlet back pressure ( from radiator) 1.4 bar 

 

so how can I apply inflow boundary condition both mass flux & pressure.

 

 

 

Thanks

    Hi Rohit,

     

    You can define the mass flux BC at the inlet and define the pressure at the outlet BC and simulate it.

     

    You can also define the above and in the advanced options, you can assign the pressure at the inlet as well, its not advisable to do so.

     

    May be we can have a web meeting accordingly, to review your model.

     

    Let us know your convenient time.

    Thanks Kamlesh,

    I have defined mass flux BC at the inlet and pressure at the outlet BC .

    solution is in progress ,Once it will converge I will let you know.
