Hi All, Sorry I wish to repost this question because I still have some problems with it. Please anyone can help me: how to simulate the magnetic field produced by 2 AC electrodes putting into a pool. I have an AC power (500Hz) with 2 electrodes, then I put the 2 two electrodes in two ends of...

many thanks for seeing, i have solved it ok

Dear All, I'd like to simulate the magnetic field produced by two AC electrodes putting into a pool (figure 1). I am using Ansoft Maxwell3D... but i don't know how to set excitation for an AC current in this case. the first test I put two current excitations at two ends of the electrodes...

sorry! It's u(x,y,z,t) = F(x,y,z,t) on S

Homework Statement The three dimensional wave equation: c∂^{2}u/∂t^2 = ∇^2 u boundary conditions : u(x,y,z,t) = F(x,y,z,t) on S initial conditions: u(x,y,z,0) = G(x,y,z) ∂u/∂t(x,y,z,0)=H(x,y,z) Homework Equations how to prove the uniqueness solution of the above equation...

Thank you very much for your instruction. But in some problems relating to flow between one source and one sink, I don't know how to map the elliptic function (Sn (z,m), Cn(z,m),...) form z plane to one half of w plane (with w=Sn(z,m))?
