NASTRAN Mesh Extractor
Mesh wrangler for NASTRAN finite element files.
Purpose is to extract node position/numbering to nodos.csv file and generate element index files for easy Matlab processing.
Only manages to extract nodes for now. Fully working executable in whittileaks.com under Elementos Finitos.
Instructions
Run executable in directory above that of the NASTRAN file, which should be in .dat format.
Follow on screen instructions (spanish). Use arrow-keys to navigate and press [ENTER]/[INTRO] to select option.
Boundary conditions (SPC) will be printed with a zero column which does not correspond to any value.
Outputs
nodos.csv
nodeNumber, x, y, z, csys/t
