Simulation in infiltration well

Post by Eliane Justino » Tue Mar 05, 2019 1:10 am

Hello,
I am trying to model an infiltration well that receives water from a roof and rain directly over an area around it.
However, I am not having success, because the vertical movement is quite small, so much so that in 48 days the infiltration does not reach even 1 meter.
I am attaching the file.
Please, if you can help me in any way.

Thanks.

I cannot open the attached file. It seems to be corrupted. J.

Thank you for your attention.
Follow the file again.
I can not attach the file.
How many megabyte can I attach?

Few comments on your project:
1. The minimum time step must be smaller than the initial time step. Make it 0.0001 h.
2. Do not change the maximum number of iterations from the default value.
3. You should select the Boundary Condition Option: "No flux when the specified nodal pressure head is negative.
4. I do not know if you realize it, but you simulate the flow in the "2D - Horizontal Plane XY", while it should likely be "2D - Vertical Plane XZ". See the "Domain Type and Units" window. This will likely be the main problem.
