Hello! I’m working with step-21 in deal.II and I’m trying to perform a *sensitivity analysis* based on *saturation front position* (S_front). Specifically, I want to compare the simulated front position against experimental data by computing the *absolute error in the x-position* of the front at a given time.
For example, in my experimental result, the front reaches *x = 5* at *time t = 0.265*. The simulation domain is a 2D rectangle of size *30 × 4*, and I’m solving a two-phase flow problem with saturation S as one of the components. My goal is to run simulations with different boundary pressure values and, at a specific time step (e.g., t=0.265), find the location where the saturation front exists, and compare it to the experimental position. What would be the best practice in deal.II to compute the x-location of the saturation front at a given time? Any advice or pointers would be greatly appreciated. I'm happy to share snippets of my code or experiments if needed. Thanks in advance!
