AbaqusReader.jl can be used to parse ABAQUS .inp file format. Two functions is
exported: abaqus_read_mesh(filename::String) can be used to parse mesh to
simple Dict-based structure. With function abaqus_read_model(filename::String)
it's also possible to parse more information from model, like boundary
conditions and steps.
Reading mesh is made simple:
using AbaqusReader
abaqus_read_mesh("cube_tet4.inp")Dict{String,Dict} with 7 entries:
"nodes" => Dict(7=>[0.0, 10.0, 10.0],4=>[10.0, 0.0, 0.0],9=>[10.0, 10…
"element_sets" => Dict("CUBE"=>[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 1…
"element_types" => Dict{Integer,Symbol}(Pair{Integer,Symbol}(2, :Tet4),Pair{I…
"elements" => Dict{Integer,Array{Integer,1}}(Pair{Integer,Array{Integer,…
"surface_sets" => Dict("LOAD"=>Tuple{Int64,Symbol}[(16, :S1), (8, :S1)],"ORD…
"surface_types" => Dict("LOAD"=>:ELEMENT,"ORDER"=>:ELEMENT)
"node_sets" => Dict("SYM23"=>[5, 6, 7, 8],"SYM12"=>[5, 6, 3, 4],"NALL"=>[…
Like said, mesh is a simple dictionary containing other dictionaries like
elements, nodes, element_sets and so on. This is a good starting point to
construct own finite element implementations based on real models done using
ABAQUS.
If boundary conditions are also requested, abaqus_read_model must be used:
model = abaqus_read_model("abaqus_file.inp")This returns AbaqusReader.Model instance.
The following abaqus elements are supported, along with the corresponding number of nodes and the elemen_types key
| abaqus element | number of nodes | element_types |
|---|---|---|
| C3D4 | 4 | :Tet4 |
| C3D4H | 4 | :Tet4 |
| C3D6 | 6 | :Wedge6 |
| C3D8 | 8 | :Hex8 |
| C3D10 | 10 | :Tet10 |
| C3D20 | 20 | :Hex20 |
| C3D20E | 20 | :Hex20 |
| S3 | 3 | :Tri3 |
| STRI65 | 6 | :Tri6 |
| CPS4 | 4 | :Quad4 |
| T2D2 | 2 | :Seg2 |
| T3D2 | 2 | :Seg2 |
| B33 | 2 | :Seg2 |
adding new elments is very easy, just look at the first lines of /src/parse_mesh.jl
