Hello,

How to add an ODE on a subdomain since ODE is (includes) a function of space variable.

Thanks,

Manohar

Hi

I would say add an ODE physics node (moel add physics ...) or have I missed something ?

Good luck

Hi,

Or for a "distributed ODE," use a PDE interface without any space derivatives.

Right now i am using a p.d.e with no space derivative but i just want to know is there any other efficient way to do that?
