Greetings,

I am farly new to comsol and i am trying to do a spiral coil.

I used workplane and I did the square spiral graph with polygon and to make the cross section circular I introduced another plane and draw circle after that I did sweep. When I try to do meshing with a cross section less than 3.5 cm i got error Face Is (Or Has A Narrow Region That Is) Much Smaller Than The Specified Minimum Element Size.

I tried to make mesh finner and no luck.

I believe that the message you quote is a warning rather than an error- that is, the model will solve although the results may be less accurate.

In any case- you probably should use more advanced meshing options. You can try some of the Comsol tutorials, for example

OR you can post your model here.
