# maxwellSym¶

Computes axisymmetric source term for the conservative form of the perfectly hyperbolic Maxwell’s equations. The source term can be used as a source in a hyperbolic algorithm to solve axisymmetric problems.

\notag \begin{align} s=\frac{1}{r}\left( \begin{array}{c} 0\\ 0\\ c^{2}B_{y}\\ 0\\ 0\\ -E_{y}\\ -\chi E_{x}\\ -\gamma c^{2} B_{x} \end{array} \right) \end{align}

Where $$c$$ is the speed of light, $$\chi$$ is electric correction potential speed factor, $$\gamma$$ is the magnetic field correction potential speed factor, $$E_{x}$$ is x electric field, $$E_{y}$$ is the y electric field, $$B_{x}$$ is x magnetic field, $$B_{y}$$ is the y magnetic field and $$r$$ is the radial position.

## Parameters¶

speedOfLight (float)
speed of light
gamma (float)
Magnetic field divergence error correction speed factor, speed=gamma*c0
chi (float)
Electric field poisson error correction speed factor, speed=chi*c0
