    Dear code Developer,
    In the Aorta example, How is it possible to change pressure outlet by time?
    (Pressure outlet is equal to 0 by default). We have two outlets in the aorta example
    is it possible to assign different pressure BC’s to them. In the main code we have just these following two lines for assigning zero pressure.
    bc.addPressureBoundary( superGeometry,4,omega );
    bc.addPressureBoundary( superGeometry,5,omega );
    Thank you


    Dear Arash81068,

    the two line asign the kind of bc. The value is set be “sLattice.defineRho”. You can define that within the time loop for changing boundary pressure values as it is done for the velocity in that very example.
