<HTML><BODY>   Dear all   has anyone had the following problem with the slab-on-grade hydronic floor plant component:   A (simple) plant network is set up and running fine. The results are plausible.   You then change the inner and outer diameters of the piping to refle! ct a real system being looked at (for the slab components and the corresponding auxiliary piping).   The effect of the change is that simulations do not run anymore, DENSIT warnings to the effect that the water temperature is not between 0 and 100 degC are written to the terminal (the temperatures given show that the calculated temperatures are "running away") and bps hangs.   I can see no direct connection between the changed parameters and the resulting program hang-up. A code check does not reveal any obvious cause / solution for me.   Does anyone have experience along these lines?   Thanks Best Achim     (symptoms are identical both for my branch and development_branch@5246) ________________________________________________________________ Diese Mitteilung wurde von http://www.breitband.ch uebermittelt.
