Multiple porous media volumes in contact

Does AcuSolve permit multiple porous media volumes that are in contact with eachother? Alternatively, can permeability coefficients be expressed as a function of x,y,z? I a modeling a tube with multiple porous zones in series however this fails on solver execution.  Example model file is attached.

 

Thanks

Ian

    It looks like some Multiplier Functions have been created somehow, one of which has type = user_function.  I'm not sure where those are in the database, or how to get rid of them, but commenting/deleting them from the .inp and running from command-prompt instead seems to allow the run to proceed - at least getting to the solver stage.

    Bingo @acupro , thanks for your help on catching the multiplier function. Multiplier functions can be accessed via the Setup dropdown on the Flow ribbon.
