Happy Monday,  
I was looking for a less memory intensive alternative (compared to julia fenics) for doing finite element method, so I wanted to try JuliaFEM. As Navier Strokes is not a predefined problem I wanted to define it my self. When adding JuliaFEM it gave me some warning messages. I couldnt paste the testing output as it goes over the caracter limit.  
I tried to follow the example of adding a problem but I could not, so I was guessing maybe JuliaFEM is not properly installed? The predefined example problems that come with it though work fine though.

```julia
type Truss <: FieldProblem
end
ERROR: syntax: extra token "Truss" after end of expression
function get_unknown_field_name(problem::Problem{Ginger})
    return "displacement"
end
UndefVarError: Ginger not defined

Stacktrace:
 [1] top-level scope at In[17]:1

```

Ping @ahojukka5

We have an active “support” in gitter: [JuliaFEM/JuliaFEM.jl - Gitter](https://gitter.im/JuliaFEM/JuliaFEM.jl) consider asking in there.

Maybe this example could help you:

I think there’s nothing wrong with the installation, `]add JuliaFEM` should be enough.

With new Julia 1.0 syntax, `type` should be `immutable struct` and if you define a problem `Truss`, you should use that name also in that function (now you use `Ginger` why the error is thrown).

I think JuliaFEM is abandoned.

Hi @PetrKryslUCSD, I want to solve 3D poissons eqn (electrostatic type problem) in julia, can you suggest good packages that are well documented as well as robust for solving large problems (~10 million DOFs).

Look at gridap, I’d say. It can even offer support for parallel execution.

Ok I will look into it and respond. Thanks

If your scope is open source but not Julia, consider Salome-Meca or Code Aster.
