### Volumetric sources
Current sources in volumes can be specified by providing a function that evaluates the current density field in a given subdomain. For example the following code defines a volumetric source in the subdomain with tag `4`:
```
function J_source(tag, x, y, z, t)
local Ex = 0
local Ey = 0
local Ez = math.sin(2*math.pi*freq*t)
return Ex, Ey, Ez
end
sources[4] = J_source
```
### Boundary conditions
### Boundary conditions
Boundary conditions are specified for each surface with tag `tag` via the table `bndconds`. If a surface does not have an entry in `bndconds` it is assumed to be PEC.
