Hello everyone

I'm trying to define the field functions in cylindrical co-ordinate. The problem case is to define the initial fluid film thickness around the cylinder with 0.1 mm thick and 0.5 mm length. The radius of the cylinder is 0.7mm. So how i define this case?

I have tried to define it as '$$position(CoordinatSystem("Laboratory.spheric"))[0] < 0.7e-3 && '$$position(CoordinatSystem("Laboratory.spheric"))[1] < 0.1e-3 &&'$$position(CoordinatSystem("Laboratory.spheric" ))[2] < 0.5e-3 : 0' but this is not working.

Can you please suggest me a different Approche for this problem.

Thank you.
