Hi everyone!
Please help.
How to set r, phi, z coorditanes for 3D modeling? They are only in 1D/2D - axisymmetric models, but i need to set some heat source in cylindrical coordinates in my 3D model.
Sorry for my bad English.

Hi, Mikhail.

Right Click on the Definitions section in your model, then Coordinate Systems -> Cylindrical System

Oh! So easy! =) Thx!)
And how can I use this additional coord. system in calculation (for example, in HeatSource that have cylindrical geometry), because new coord. system don't replace old system....? In x,y,z system it is Q(x,y,z). After adding the new system, the program still does not see the new coordinates and record Q(r,phi,z) does not work. Maybe I should be so set Q(sys2(r),sys2(phi),sys2(z))??

In physics for some domains you can choose Cylindrical System under Coordinate System Selection (by default it's Global Coordinate System).
