Current Density components in Body Force Section

Post by srinathshiv »

Code: Select all

Body Force
  Current Density 1
  Current Density 2
  Current Density 3

end
What does 1,2,3 mean. How do i change these components if I want to input
current density as 2 nA/units*units .

Hi,

curent density is a vector, and those are its components (x,y,z).
Elmer assumes SI units by default, so you must give your values in multiples of A/m^2, e.g.

Current Density 1 = 1e-9
Current Density 2 = 0
Current Density 3 = 0

for a current density of 1 nA/m^2 in x direction.

HTH,
Matthias
