A question about the following comment from iRIC Nays2DH

I am using Nays2DH solver, and the following message pop-up on the Solver Console:

「The number of deposited layer exceeds the maximum number 50 at i= 96 j=22
Please change the thickness of deposited layer, thickness of movable bed layer or the maximum number of deposited layer.
Fortran Pause – Enter command or to continue.」

The question is that how can I edit the mentioned parameters without cancelling the simulation. I tried to update the thickness of movable layer but had to cancel the calculation and restart.
please kindly drop the answer if you know.

    Hello, please refer to the following and change the settings.
    Q: I don’t know how to set the grain size distribution of the exchange and sediment layers.
    A: There are many ways to do that, please refer as an example.
    “Thickness of bedload layer” : Maximum grain size(dmax) or d90 etc.
    “Thickness of deposited layer” : 2dmax etc.

    Thank you for the reply.
    I could change/set the thickness and number of layers after cancelling the simulation. I am wondering, if we can change the mentioned parameters while the simulation is not cancelled/restarted.

    Thank you.
