Units in global ODEs

I am creating a model that uses global ODEs to provide values for boundary conditions for a domain-based PDE model. The PDE model variables can be fully populated with units but the global ODEs appear to be dimensionless. Expressions built using the global variables and model variables end up with the wrong units. Is there a way to apply units to the variables defined in the global ODE node? I have searched the documentation without success.

Hi

Indeed I see tha too, (but only the global ODEs) not sure why, one would have to ask support ;)
But you can always multiply the dependent variable by 1*[my_units] all over ;)

Good luck
