Dear Dumux Team,I am currently beginning with Dumux and trying to simulate processes in the soil.
Currently I am focusing on microbial processes (i.e. only ODEs) but I want to keep using dumux so that I can keep using the results in the full-scale simulation of the soil processes.
In order to fit the parameters, I want to compute local sensitivities for the parameters, so derivatives of the form \frac{\partial solution(time t)}{\partial parameter_i}.
When looking through your old mails I found one from mai of 2020 (it has a different topic):
From dmitry.pavlov at outlook.com Fri May 15 18:25:33 2020 From: dmitry.pavlov at outlook.com (Dmitry Pavlov) Date: Fri, 15 May 2020 19:25:33 +0300 Subject: [DuMuX] Analytic Jacobian in the case of variable viscosityMessage-ID: <he1p191mb025295a4da86fc5f5043d245ff...@he1p191mb0252.eurp191.prod.outlook.com>
In its answer on the same day Timo Koch wrote “(A[utomatic ]D[ifferentiation] would be an option but currently not implemented in Dumux)”
Has automatic differentiation been implemented since?And do you know of an automatic way to calculate these local sensitivities? Or has someone else tried it before in another application using dumux?
Kind Regards, Erik
