General PDE declaration

Hi,

the Code-Aster features include several standard problems as for example structural analysis, heat equation etc., but I hope that you are not limited to solve the predefined problems.

Is it possible to solve general partial differential equations, and how would you define them in Code-Aster?

For comparison, I had a look into the description of OpenFoam, and in section 3.1.3 ( www.opencfd.co.uk/openfoam/doc/userse4.html#x9-640003.1 ) you find an example
[code:1] solve
(
fvm::ddt(rho, U)
+ fvm::div(phi, U)
- fvm::laplacian(mu, U)
==
- fvc::grad(p)
);[/code:1]
for a general diffusion-advection equation.

Is something similar possible with Code-Aster?
