Questions tagged [pde]

Use this tag for questions about partial differential equations. For questions about the Eclipse Plugin Development Environment, use eclipse-pde instead.

Partial Differential Equations are differential equations that contain unknown multivariable functions and their partial derivatives. See [http://en.wikipedia.org/wiki/Partial_differential_equation][1]

The Eclipse Plug-in Development Environment (PDE) provides tools to create, develop, test, debug, build and deploy Eclipse plug-ins, fragments, features, update sites and RCP products. PDE also provides comprehensive OSGi tooling. See [http://www.eclipse.org/pde/][2]

Questions about the Eclipse Plug-in Development Environment are better tagged as 'eclipse-pde'.

In matter of PDEs, can I use ODE solvers for each step?

I have equations like this: wl[n]= w[n] + Δx*v[n] ϕl[n]= ϕ[n] + Δx*ρ[n] ρl[n] = ρ[n] - Δt*fρ(ρ,v,w,n) vl[n] = v[n] - Δt*fv(ρ,v,w,Δx,n) Simulating these equations: Can I use ODE solvers to do it in time, then in space. Or, else, is there a Julia…
