Physics controlled mesh in 4.0

Hi
Is it possible to create a physics-controlled mesh in the version 4.0? I know that 4.1 can do it, but I'm not sure how to do it in 4.0.
I'm working with non-isothermal flow, so I need to make the mesh smaller around the inlet area otherwise it wont converge, how can I do this?
Thanks
Elizabeth

Hi
if I remeber right the "physics induced" mesh in 4.0 was very limited, really nice in 4.1, with new improvements, enhancements for more physics for 4.2. In 4.0 I only trusted manual meshing, but you have full control manually, its just somewhat tediuos. As meshing is almost an "art" you learn a lot by meshing manually though.

Good luck

Dear Ivar,
I am using the 5.0 version.
I want little bit clarity over using the physics controlled mesh. As it is explained in the help -- it can be used when the wavelength changes in different dielectric regions. Does it mean when they are combinely used or individually?? What about the usage in case of sandwich type structres like metal-dielectric-metal structures media is not uniform on which I am trying to work now ?? how about the relation between the background wave type and meshing in this case , as I wanted to calculate the scattered field now .
I used two physics nodes, the first one solves for the background electric field(y-component, norm) for the air-glass domain without the MIM and the background field drawn from this physics will be used to claculate the total field (y-component, norm) in the second one. for that I defined a set of variables the E-field components as "0".
I am brand new to comsol, trying to learn. I will be glad with your patient reply. hope my question is clear to you.
I took the scatterer on substrate as a model example to follow my structure.

Srivathsava Surabhi.
