Simulation may have completely dried out

Question

Hello, HydroNumerics team.

I hope everything is going well.

While using AEM3D models, there is an error that has not been resolved for several days.

I've seen related issues on here forum, but I haven't been able to solve them in my model.

The issue is as follows:

09:28:18  INFO:  * NOTE: DEFAULT_BC is FREESLIP_ALL
09:28:18  INFO: Step:  1/15 SimDate: 2000-01-01 00:00:00 (2000001.0000)  Time: 09:28:19

23:31:21  INFO:  * No surface area found
23:31:21  INFO:  * Simulation may have completely dried out

Can you tell me the reason for the error and how to fix it?

Thank you.

Regards.

Hi Jaeyoung,

The "No surface area found" area means that there is no volume in your water body.

As this is your 1st timestep it looks like your initial height is incorrect.

This is set using the DEFAULT_HEIGHT keyword in run_aem3d.dat.

Make sure it is above the bottom of your bathymetry
