I'm very new to COMSOL Multiphysics 5.2a
I would like to create long (5 m) and thin ( d = 30 micrometers) tungsten wire sagging in the gravitational field, having electric potential 1800 V with fixed ends.
Moreover, this wire is surrounded by long tube of the same length with inner diameter 9.8 mm and outer 10 mm, which is grounded and has fixed ends as well.
Between wire and tube should be air.
So there is some electric field between wire and tube.
Sagging of the wire due to gravity causes breaking of symmetry of the electric field and this deformed field deflects wire even more.
I would like to calculate displacement of the wire and tube in such feedback model with crossed electric and gravity fields.
I suspect have to use prescribed mesh displacement (maybe no!) but details still unknown.
Any help would be appreciate!
Best regards,
Borys
