Surface is too high for domain: Face c

Question

Hello,

I have been using the AEM3D - CAEDYM, the model ran without any problem when I set the initial conditions varying horizontally for chlorophyll but I have the follow error when I set the initial conditions varying horizontally for Sea Surface Temperature:

12:06:35  INFO: Step:     1/54720 SimDate: 2018-01-01 00:00:00 (2018001.0000)  Time: 12:06:35

12:06:35  INFO:  ***** FATAL ERROR **** FATAL ERROR **** FATAL ERROR *****

12:06:35  INFO:  * in subroutine get_surface_and_bottom_maps

12:06:35  INFO:  * Surface is too high for domain: Face c

12:06:35  INFO:  *   Column:       2280 i:        64 j:        17

12:06:35  INFO:  *   Height:    0.398E+04

Thanks for the help!

Answer 1

Hi Diana,

This means that your water level has reached a level which is higher than your total height in your bathymetry file (the bottom cell of your bathymetry plus the sum of the dz values).

This may be a volume issue (too much inflow or not enough outflow) or maybe an instability in the surface solution (you can reduce dt).  Or you just may need to add more z levels.

Chris, thank you so much!

Yes, thank you. I had the same error.

Hi all

After quite a bit of head scratching I finally figured it out why I kept getting this error. Interestingly, it was caused by a strong wind event blowing from west to east along Lake Erie which caused a seiche event and was unrelated to inflow/outflow. One more thing to keep in mind.
