  1. Dear all,

    I hope you are doing well.

    I am currently facing an issue with the Recharge package in my MODFLOW model and would appreciate any guidance.

    When I assign even a very small recharge value, the model fails to converge and returns an error. Interestingly, the same problem occurs even when I deactivate all other boundary packages (such as GHB and River) and keep only the Recharge package active.

    However, when the Recharge package is turned off or the recharge rate is set to zero, the model runs successfully without any issues.

    This is the second time I am posting about this problem. I would be very grateful for any suggestions or advice, as I am currently stuck at this stage.

    Thank you very much in advance for your time and support.

    Best regards
