Hello guys,
I have the system of PDE below and I want to solve it using finite difference method but I think I have to reduce it first to a system of first order PDE. The problem is that I don't know how to reduce this PDE to a first order system. I will appreciate any hints in this regard. Thanks
∇6w1 + μ1∂/∂t(∇4w1) + μ2∂2/∂t2(∇2w1) + μ3∇4w1 + μ4∂3w1 /∂t3 + μ5∂/∂t(∇2w2) + μ6∇2w2 = g1(x, y, t)
∇6w2 + χ1∂/∂t(∇4w2) + χ2∂2/∂t2(∇2w2) + χ3∇4w2 + χ4∂3w2 /∂t3 + χ5∂/∂t(∇2w1) + χ6∇4w1 = g2(x, y, t)
