Default ODE Solving in OpenFOAM

Hi,

I need to solve two ODEs during the main solving loop for my PDEs. I basically need to solve Newton's Equation F = ma and T = Ia for rigid body motion. I saw that there is a special solver for 6dof motion, but I would like to solve these two equations only.

I can't find any good tutorials online or some sample code for solving ODEs. Is there any sort of material online?

Had you had a look at
http://hassankassem.me/posts/ode/ ?

In general you can use any PDE solver for solving an ODE. This might be overdone, but it works. I only tried combining solving a PDE with an ODE. For this purpose I created a new field variable and added the additional equation in the solver code (only using the temporal derivative) resulting in a modified solver.

Were you able to integrate them, I am also interested in learning.

Hi! ,
Do you have luck finding out how to solve and ODE inside the loop of a PDE?

This post http://hassankassem.me/posts/ode/ and this http://www.tfd.chalmers.se/~hani/kur...rtZongyuan.pdf publication explain how to solve an ODE but none of them eplain how to use it along with a PDE solver.
