Hello,

i tried to simulate a closed system with natural cirulation. The geometry is shown in the attached picture. The simulation works and now i am trying to inclued a additional pressure loss coeffizient (zeta-value) between the absorber (red) and the cooler (blue) in order to reproduce reality better.
Does anybody know if (and how) there is a possibillity to include an additional pressure loss coefficient as a UDF instead of redrawing the geometry for each value of pressure loss coeffizient. Thanks!
