Dynamic mesh increase or decrease during the computation

    • debuger


      I used dynamic mesh to simulate the process of piezoelectronic fan. The simulation is three dimensional,I have some quesstion about the dynamic.

      1) Why the number of the mesh increasing with the iteration,but  the mesh decreasing with the iteration for other case.

      2)Why the case which with stable mesh number in computer with less CPU during the iteration will increasing or decresing the mesh number in more CPU condition(8CPU is ok, but 140 CPU the mesh decreasing rapidly.....)

      I use the sizing function but it seems did't work well. I also changedthe Minimum cell length and Maximum cell length but sometime it work well but sometime is poor....

      Anybody can give me some suggestions?thx
