Hey. I am attempting to create a tidal simulation, for which I need to turn off the hydraulic head boundary whenever each node is above sea level. I have a code that deletes the values of each time series of each node where the head values are below the node elevation, but I cannot seem to insert a gap, as the IFM code wants a numeric value for each time step. I could do it manually but the is too much work for too many nodes, and I believe there must be a way to do it with code, or perhaps another way.

Hey, I was wondering how could i extract the rate budget of mass/fluid per node from a specified node range? it is very easy to extract that info for a bunch of nodes, or a single node, but i couldn't find a way to do it for every node within a specified range separately. Thanks in advance Adam

Hey. I am trying to run a variably saturated, mass transport model. The goal is to recreate glacial / interglacial groundwater simulations of saltwater intrusion. however, the model will always end up stuck in a loop where an area gets excessively concentrated areas (different areas in the transition zone each time), where I end up with a tiny area that has impossible concentrations, as well as negative concentrations at the landward side. I have tried to make a smaller mesh, and to make the time series of the sea level rise and fall in constant steps to reduce computation costs. I guess my question is, if anyone has prior experience with this type of issues, how to make a transient state model not to loop due to mass transport issues, and how to make such a model run for thousands of years, without it actually taking thousands of years.
