NastranResults

Load MSC Nastran OP4, PCH and HDF5 results into Julia.

Installation

To install, write in the Julia REPL

julia> ]
pkg> add https://github.com/mgcth/NastranResults.jl.git

Documentation

Support for output data loading, only. Currently supports:

• OP4 (OUTPUT4):
  • Supports real double precision binary sparse non-BIGMAT and BIGMAT matrices
• PCH (PUNCH, SORT2):
  • SOL103, real valued modal data, single precision
  • SOL108/111 complex frequency response data, single precision

Usage

Example of usage

julia> using NastranResults

# find matrices in file, output vector of strings
julia> mnames = readop4("filename.op4");
julia> mnames[1]
"KAA"

# load specific matrix
julia> mat = readop4("filename.op4", "KAA");

# load all matrices in a vector of tuples (name, matrix))
julia> mat = readop4("filename.op4", "ALL");

# read SOL103 punchfile
julia> mat = readpch("filename.pch", PunchModalData);

# read SOL108/111 punchfile
julia> mat = readpch("filename.pch", PunchFrequencyData);

Roadmap

• Add testing
• Improve performance of op4 loader
• Read more PCH types
• Read HDF5 result, have code but needs structuring
