Hi,
is there a simple way to monitor bed expansion for TFM or PIC simulations? I have been considering to use a plane and try to extract the “wetted area”, perhaps divide by the section width (afterwards). But I can’t find any appropriate data points for this purpose, as both volume fraction and density will not change according to a wetted area. Are there other ways to acheive this?
Would statistics of particle Y-coordinate help? We support mean and standard deviation as monitors.
