Hello to all you very helpful people!

I have a question regarding a FSI Model I am setting up for the interaction between bone marrow (behaving like a non-Newtonian fluid)
and trabecular bone tissue. I am interested in the solid part right now.
As a result of load, the density of the bone tissue changes (based on a microstrain threshold).
Thus, I would need to have a variable rho in my properties for the solid domain.
How do I do that?
I assume there is a way to get the solidProperties as a variable that can change with each time step.

I am really still at the beginning of using OpenFOAM. So i might have left some information out that are necessary to help out.
Please let me know if I need to post any more details.
Many thanks

Evelyn
