I am doing a 2D single phase simulation for a check valve.
I am trying to move the valve in the negative x-direction using the Udf given in fluent dynamic mesh tutorial. The Mesh is shown in figure 1 (Please See Attachment Figure.1 & Figure2) when I am trying to do the unsteady state simulation following message is dispayed "Non-Positive volume exists" Error: divergence detected in AMG solver: x-momentum Error Object: () and the grid looks like shown in figure 3 (Please See Attachment) figure1.jpg figure2.jpg figure3.jpg |
