Cyclic option is not activated
Hi Samah.
By “Cyclic option is not activated” I think you mean this tab in the Boundary Conditions pane:
That is only activated when a cyclic boundary condition is present. In MFiX, Cyclic BCs are treated a special type of boundary, to add one click the ‘+’ icon and select Cyclic for type
and then you can specify which direction to apply the cyclic boundary:
Once the cyclic BC is present and selected, the conditions can be edited:
