JuliaFEM / AbaqusReader.jl

AbaqusReader.jl is a parse for ABAQUS FEM models. It's capable of parsing the geometry accurately, including surface sets, node sets, and other relevant geometrical data used in FEM calculations. Other option is to parse whole model, including boundary conditions, material data and load steps.

Beam elements not supported. #40

Closed vjamsa closed 6 years ago

vjamsa commented 6 years ago

AbaqusReader doesn't support beam elements even though 2 node cubic beams are implemented to JuliaFEM in FEMBeam.jl. The 2 node cubic beam element in space is B33-element in Abaqus.

We've had some discussion in the past on Gitter on how much support this reader should provide. Look around March 6th.

I think it's quite straightforward to read the geometry of beam structure from ABAQUS file, but the properties are the harder one then.

Im trying to read this input file:

*Node
      1,         240.,        1090.,        147.5
     74,   244.285721,   1114.28577,   173.357147

3, 75, 76

6, 78, 79
7, 79,  2

And im getting this error message:

I fixed bug related to parsing regexp and B33 element is now supported. See PR #42.
