Calibrate the modeling with the nodes inside the modeling area

Post by eesly » Tue May 13, 2025 7:32 am

I would like to know how to calibrate the modeling with the known water level inside the modeling area rather than on the boundary?

You can calibrate measured values inside of the domain by using Observation Nodes at the same location. J.

When boundary conditions are defined at a low level, the modeling area (configured at a high level) cannot achieve elevated results in simulations due to restrictive boundary constraints
