Assuming incompressibility of the fluid, the viscous acceleration simplifies to $$\frac{d\textbf{v}}{dt} = \frac{\eta}{\rho} \nabla^2 \textbf{v}$$ In Price 2012 the second derivative of a vector is given as  where ...
As seen in #262, a two-way coupling of fluid and structure is not that trivial. I suggest spending more time on literature and then implementing an interface for coupling single...
For some methods such as TVF and OpenBC an update each full time step is necessary. That makes the update callback in #440 mandatory for a simulation. We can't just...
As discussed in #437: https://github.com/trixi-framework/TrixiParticles.jl/pull/437#discussion_r1543045977
