question about Water flow velocity

[ZhouYmi]

Dear Pere@fronterapp ,

I would like to ask if I can directly input the water flow velocity at this location in the logLawInlet file you wrote, for example, by changing it to:
else U[i] = vector(0.1, 0, 0);
Finally, I would like to thank you for providing this code and for your assistance in maintaining it. I'm looking forward to your reply.
Best,
Zhuo

Dear Zhuo,

Thank you for reaching out and for your kind words.

Regarding your question, the current condition in the logLawInlet file specifies a logarithmic velocity profile above z_ground and assumes zero velocity below that. Since the condition does not specifically differentiate between phases of flow (e.g., air or water), it should indeed be possible to directly input the water flow velocity as you suggest.

Please feel free to implement this and let me know if you encounter any issues or have further questions. I'm happy to assist!

Best regards,
Pere
