nastran_pch_reader

parser of NASTRAN punch files.

Module currently support the following outputs:

• solution sequences: SOL101, SOL111
• requests: MPCF, SPCF, ACCELERATION, DISPLACEMENTS, FORCE (only for CBUSH and CELAS2)
• sorting: SORT1 and SORT2
• representation for frequency response: real/imaginary and magnitude/phase

Example:

import nastran_pch_reader
parser = nastran_pch_reader.PchParser('test-data/sol101.pch')
# summary of the forces at the elements
for element in [3000, 3001]:
        print('Element force at %d' % element)
        for subcase in parser.get_subcases():
                forces = parser.get_forces(subcase)
                fx, fy, fz, mx, my, mz = forces[element]
                print('\t subcase',subcase, '=>', (fx, fy, fz))
