Hello,

I'm trying to define following setup:

duct with 1 inlet and multiple outlets, axisymmetry, compressible (ideal gas), subsonic

known inlet parameters: m_dot, p_total, T_total these parameters are fix, i know that you cannot define each of these parameters at once when subsonic

known outlet parameters: delta_m_dot on each boundary the loss of m_dot_initial is known. ONLY delta_m_dot known at this borders (no ambient pressure). so i need a massflow sink.

thats it.

i tried many variations (also outflow) it seems to be a big problem, that it is compressible.

how can i solve this problem.

regards
