Hello,
I have inherited a MODFLOW-model, with a complex stream network defined with the SFR2 package. The model checker reports that many of the stream segments have the error "ELEVUP or ELEVDN is below a cell bottom elevation...". The original MODFLOW model uses MODFLOW 2000, which reported the error, but would run regardless. However, when the version is changed to MODFLOW 2005, the model terminates with error due to "reach altitude error" (as written in the .out file). It is important that the model can run with MODFLOW 2005.
Is there a way I can force MODFLOW 2005 to run the mode
