I have simulated 48 hours of flood event in NAYS2D Flood solver but model ran only 19 hours and subsequently “Calculation is failure” message appeared. Can anyone help me on this matter.
I suggest that you try follows.
1. Set “Calculation time step” more small.
2. Change “Calculation grid distance” more wider.
3. Change “Elevation” when fast flow is calculated before appearing “Calculation is failure”.
Could I ask u some qusetions about meandering river by nays2d ,plesse?in case ,this is my email:firstname.lastname@example.org,also, you can leave your email for convience.
Thank you very much for the reply. I will follow as you said.
