A Ruby script that reads Nastran BDF file
Purpose of the script
The script illustrate the reading of Nastran model from BDF file with FeResPost ruby extension.
Script
require "FeResPost"
include FeResPost
# Creates and initializes the DataBase :
db=NastranDb.new()
db.Name="tmpDB1"
db.readBdf("../../MODEL/MAINS/unit_xyz.bdf")
db=NastranDb.new()
db.Name="tmpDB2"
begin
db.readBdf("unit_xyz_V1.bdf",["../../MODEL/MESH/"],"bdf",{},true)
rescue Exception => x then
printf("\n\nMaybe you should modify the two first include statements in main file!\n")
printf("**********************************************************************\n\n")
raise x
end
Explanation
The different steps of the Nastran FEM importation are:
- The access to FeResPost compiled library.
- The creation of a NastranDb object by a call to “NastranDb.new()” method.
- The importation of the model from a BDF file by a call to “readBdf” method.
Note that in te example above, the model is read twice. The second reading illustrates several optional argument of the “readBdf” method.
