Problems with mass imbalance
 
Hi all,

I want to check the mass imbalance of my calculation. It's a cyclone separator with Air and as the lagrangian phase H2O. I activated the option boundary sampling in the lagrangian phase.
My boundaries are inlet, outlet, wall and I have the lagrangian phase. What kind of report do I have to choose to display the mass imbalance? And what vector and parts do I have to select?

regards

You can use sum report, then select the boundaries in parts and select the field function of boundary mass transfer.

why does the following error occur?

"An internal error has occured. please contact your support.....

Attempt to access unallocated massImbalance storage in cells in Body 1"

I get this error when i try to run a previously saved run. How can we overcome this error?

Thanks

The mass imbalance function calculate the imbalance for each cell. Have you removed any cell?
Anyway, as I told you, if you want to see how is the mass imbalance ( continuity), a Sum report will help you.
