Hello All,
I faced a problem while modeling a shallow lake. I run the model first with the time step of 30s and it takes around 2 hour to finish 1000 No. of time steps. I decided to increase the time step to 180s with the same number of steps to cover more days in my simulation and I expected the model finish around 2 hours again because number of time step did not change and still it was 1000 but surprisingly, simulation time takes around 10 hours !!
Number of elements 13848
Number of nodes 9433
Smallest Area 103 m2
Largest Area 4.5 km2
Does anyone know what is the problem here?
Any suggestion to solve this problem would be highly appreciated.
Thanks.
Mohammad
