NASTRAN

This option can be used to read in data from from NASTRAN PCH files.

Currently the following types and data components are supported along with the SORT1, SORT2 and XYPUNCH file formats

Nodal Displacements
Nodal Velocities
Nodal Accelerations
Nodal SPC Forces
CBUSH Element Forces
CDAMP Element Forces
CELEM Element Forces
CBAR Element Forces
CQUAD Element Forces
CTRI Element Forces

By default T/HIS will read in every curve that it finds in the file so if you read in a file containing nodal displacements from a SORT2 format file you will end up with 12 curves being produced in T/HIS for each node.

X,Y,Z translation (Real) / (Magnitude)
X,Y,Z translation (Imaginary) / (Phase angle)
X,Y,Z rotational (Real) / (Magnitude)
X,Y,Z rotational (Imaginary) / (Phase angle)

The Options... button will display the following menu that will allow some components to be deselected before reading the file.

Complex Data For complex data components written out as a pair of real and imaginary numbers or as a magnitude and phase angle either of the components can be deselected.
Nodal Data For nodal data any of the 4 data types can be deselected along with any of the 6 translational/rotational directions.
Element Forces For element forces each individual element type can be deselected.

T/HIS will automatically create curve labels for each curve generated from the PCH file. The entity types, ID's and components will also be stored with the curves to allow the curves to be sorted using the curve table (see Table )
