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.
