Hi, I am a beginner in Julia and I am learning JuliaFEM atm.
I added the JuliaFEM and LinearAlgebra Package.
but when come to:

mesh = aster_read_mesh(meshfile)

then comes message as follows:

MethodError: no method matching get_nodes(::AsterReader.MEDFile, ::Dict{Int64,Array{String,1}}, ::String)
Closest candidates are:
get_nodes(::AsterReader.MEDFile, !Matched::Dict{Int32,Array{String,1}}, ::String) at C:\Users\21631933.julia\packages\AsterReader\LfzMD\src\read_aster_mesh.jl:119

Can anyone helps me with this issue？
THANKS.

Hi @Sukhe1993,
You will need to give a file name as a string:

meshfile = joinpath(datadir, "JuliaFEMSMP18.med")
mesh = aster_read_mesh(meshfile)

This equals:

mesh = aster_read_mesh( "datadir/JuliaFEMSMP18.med")

Here is the full example: https://github.com/JuliaFEM/JuliaFEM.jl/blob/master/examples/linear_static.jl and here is the mesh file: https://github.com/JuliaFEM/JuliaFEM.jl/tree/master/examples/linear_static

I just noticed that instead of datadir it should be linear_static in the above example.

Thanks, TeroFrondelius,

I gave the name same as the example below and follow the example below.
http://www.juliafem.org/JuliaFEM.jl/latest/examples/2d_hertz_contact.html
However, it still doesn't work.

No such file or directory

Please download the med file to the same directory you are running the example and change the command to have just the file name.

Most of the output is because the documentation generation is failing. Did you already resolve this problem? Anyway, the problem seems to be quite trivial. You just need to have your script and mesh file in the same directory. This is working for me:

using AsterReader
meshfile = download("https://github.com/JuliaFEM/AsterReader.jl/raw/master/test/test_read_aster_mesh/quad4.med")
mesh = aster_read_mesh(meshfile)
println(mesh)

Now AsterReader.jl is giving more clear error message when user tries to load file not existing.
