ACUSOLVE error in boundary condition

HI,

I am new to ACUSOLVE. I have a flow problem in which I have assigned a pressure inflow and an outflow with mass flux using advanced boundary condition.

When I try to run the solver, I am getting an error stating ' multiple surface integrated condition at outlet'

I don't understand the actual sense of this error since as far as I know, we can simulate a case with an inflow pressure and outflow mass flux. I have done similar cases in ANSYS Fluent.

 

If somebody knows how to rectify this problem, please let me know asap.

 

Thanks in advance.

    Is there a particular reason for using these advanced BC? If possible stick to SImple BC, as they are generally stable. Advanced BCs are generally recommended to be used by experienced users.

    Hi, 

     

    Thank you for replying.

     

    I have to maintain a particular inlet pressure and an outlet mass flux as per the problem. In AcuSolve, I have only seen mass flux option for outflow in advanced boundary conditions page. 

    Or,

    Is there any other method to specify these boundary conditions to the solver?

     

    Also, I have one more doubt regarding setting of interface boundary in AcuSolve. Can we have an interface boundary for non matching faces in AcuSolve? If yes, how can we set it and how does AcuSolve consider the non matching faces?

    The the advanced BC is the option for setting up the outlet mass flux BC. 

     

    Check the tutorial/workshop ACU-5001: Blower - Transient (Sliding Mesh) from AcuSolve 2017 tutorials for an example on non-matching faces.
