Inspecting Results contained in a DataBase

IV.2.4.1 Inspecting Results contained in a DataBase

The following example prints the information on Results available in the DataBase. It starts with the following lines:

   require "FeResPost"
   include FeResPost

   #DataBase::disableLayeredResultsReading
   #DataBase::disableSubLayersReading("Bottom")
   #DataBase::disableSubLayersReading("Mid")
   #DataBase::disableSubLayersReading("Top")

The commented lines are methods that disable partially or entirely the reading of composite element layered Results. After reading the corresponding manual in section I.1.3.2, you may un-comment some of these instructions to check the effect on the reading of composite Results.

The main part of the example program looks like this:

# Reading or generating Results :

   db.readOp2("../../MODEL/EXEC_OP2/unit_xyz.op2","Results")

   db.generateCoordResults
   db.generateCoordResults("Fake Coords Case","No SubCase","coords")

# Inspecting and reading Results :

   db.each_resultKeyCaseId do |lcName|
      printf("LOADCASE: ' "%s' "' n",lcName)
   end
   db.each_resultKeySubCaseId do |scName|
      printf("SUBCASE: ' "%s' "' n",scName)
   end
   db.each_resultKeyLcScId do |lcName,scName|
      printf("LOADCASE and SUBCASE: ' "%s' " - ' "%s' "' n",lcName,scName)
   end
   db.each_resultKeyResId do |resName|
      printf("RESULT: ' "%s' "' n",resName)
   end

   db.each_resultKey do |lcName,scName,tpName|
      tmpRes=db.getResultCopy(lcName,scName,tpName)
      printf("%-20s%-15s%-50s%-10d' n",lcName,scName,tpName,'
             tmpRes.Size)
   end

It works as follows:

The call to method “readOp2” loads Results into the DataBase.
One also generate coordinate Results.
Then one builds three lists containing the load cases, sub cases and type names of all the Results contained in the DataBase. Those are three Array of String objects. Their respective contents are printed.
One uses several iterators that read the lists of load cases, subcases and Result identifiers and prints the output.
Using the iterator “each_resultKey” one obtains copy of the Results stored in the DataBase, prints the corresponding key identifiers, and the corresponding size.

The example is provided in file “RUBY/EX04/printResLists.rb”.

Another example illustrating the reading of Results from a Nastran OP2 file is provided in file “RUBY/EX04/printResLists_filter.rb”. This example illustrates the use of “readOp2FilteredResults” method.
