A Ruby script that reads Nastran HDF file
Purpose of the script
The script illustrate the reading of Nastran Results from an HDF file.
Script
require
"FeResPost"
include FeResPost
require "../UTIL/util"
Post.loadHDFLibrary("C:/NewProgs/HDF/HDF-1.8.20-win32/bin/HDF.dll")
#~
Post.loadHDFLibrary("C:/NewProgs/HDF/HDF-1.8.20-win64/bin/HDF.dll")
dirName="D:/SHARED/FERESPOST/TESTSAT/MODEL/EXEC_HDF"
baseName="unit_xyz"
lcIndex=0
scIndex=0
bdfName=format("%s/%s.dat",dirName,baseName)
hdfName=format("%s/%s.h5",dirName,baseName)
xdbName=format("%s/%s.xdb",dirName,baseName)
db=NastranDb.new()
db.readBdf(bdfName)
db.attachHdf(hdfName)
lcNames=db.getHdfAttachmentLcNames(hdfName)
lcName=lcNames[lcIndex]
scNames=db.getHdfAttachmentScNames(hdfName,lcName)
scName=scNames[scIndex]
resNames=db.getHdfAttachmentResNames(hdfName,lcName)
hdfResNames=resNames.clone
db.readHdfAttachmentResults(hdfName,lcName,scName,resNames)
...
Explanation
The different steps of the Nastran Results access from HDF file are
- The loading of HDF dll library. Remark that must one choose the right version depending on the version of ruby one is running. For example, on Windows one must choose the appropriate 32bits or 64bits shared library.
- A Nastran HDF Result file ("h5" extension) must be attached to a NastranDb database.
- Then, one can access to information about the Results stored in the HDF file. Results can be read into the Database, or returned into a Hash object, as in the example above.
