    How to make cut plot legends auto-update based on min/max values?

    Dan Hofstetter

      I have been working on a tank flow simulation where a fan forces clean air into the tank to remove hazardous gases.  I set up a transient simulation, and it seems like sometimes the default cut plot I insert for gas concentration will automatically update the min/max values based on the actual min/max levels at each time step.  However, if I manually adjust the legend range in the cut plot, all subsequent cut plots in the series use the new range for display purposes, making it difficult to see differences throughout the tank when the gas levels drop below the minimum legend value.  I have not had much success getting these values to go back to automatic.  The only thing I have found that seems to work is to delete the cut plot, exit Solidworks, restart, and insert a new cut plot with default legend scale range values.  Is there another way of controlling this?

       

      Another related question:  I have the initial tank concentration set at 143 ppm H2S.  The floor surface of the tank emits pure (1,000,000 ppm) H2S based on a time-decay function.  When the surface source is suppressed, my cut plots show the maximum tank level of 143 ppm as the maximum legend value.  When the surface source is enabled, the automatic legend max value jumps to 1,000,000 ppm.  The floor surface emits a very low level of H2S compared to the 143 ppm level in the tank, so over time its effect is almost negligible, but I have to include it for comparison to results from another CFD package.  Is there a workaround so the auto legend entry never goes above the 143 ppm value but will still scale downwards as the max level in the tank drops?

       

      Thanks,
