Please login with a confirmed email address before reporting spam

Dear Concern,

Hope you are fine.

I am working on the drug implant system. As I have to apply flux boundary condition at the center r0(mentioned in the attached 1). As flux is given in (attached flux), I found flux by using global ODE. And the flux boundary condition is given in (attached flux boundary condition). As I am using transport of diluted species whenever I select boundary condition for r0 (inner circles except outer) it shows me in aplicable. Can you please guide me how can I apply flux boundary condition. Attached are the pictures for reference.

Hope to hear back soon. Thanks
