Shear solver instabilities #227

Closed maddykelley closed 1 month ago

maddykelley commented 1 month ago

After chatting with Bart, I believe we identified an issue with the shear solver. Instabilities appear in the first few timesteps. In this example, the wind magnitude changes, but the direction remains constant. I noticed the same issue in other test runs on the fluvial-aeolian discussion board as well. I’m fairly confident that I need to use the 'shear processes' to produce the correct erosion/deposition patterns linked to topographic effects.

I've attached all my input files. I can email the output files (too large to upload) input.zip

Bart, am I missing any important info?

The shear solver seems to have some issues with your current topography. A more detailed answer is given in Discussion #219

I close this issue because of the ongoing discussion about this here #219
