PDE Systems.


Anyone know of a package to solve systems of partial differential 
equations in Mathematica (even linear ones)?

I tried the following in mma2.23:

DSolve[{D[f[x,y],x]==0,D[g[x,y],y]==0,D[f[x,y],y]+D[g[x,y],x]==0},
  {f[x,y],g[x,y]},{x,y}]

And got the message:

DSolve::pde: Partial differential equation encountered.
