Hello everyone.

Tell me how to solve this equation grad(div(f(x,y,z)))+K*Laplacian(f(x,y,z))=0

Here, the function f defines a vector field.

I tried so

restart

with(Physics[Vectors]):

Physics:-Vectors:-Setup(mathematicalnotation = true)

[mathematicalnotation = true]

 (1)

eq := Gradient(Divergence(f(x, y, z)))+K*Laplacian(f(x, y, z)) = 0

Error, (in Physics:-Vectors:-Nabla) Physics:-Vectors:-Divergence expected a vector function, but received the scalar function: f(x, y, z)
