Interfacing with PAM-CRASH 2G

This section discusses how the HyperGraph applications interface with the PAM-CRASH 2G solver.

HyperGraph hgdaisy External Reader


Description	Supports	Does Not Support
Reads PAM-CRASH and PAM-CRASH 2G DSY files (results files generated by the solver) into HyperGraph. The PAM-CRASH DSY reader is enhanced to handle higher version result files. No ESI license is required to use this reader.

Usage

To run from the command prompt to convert PAM-CRASH or PAM-CRASH 2G DSY files into Altair Binary Files (ABF files):

-hgdaisy dsyfile outfile.

To run in HyperGraph:

By default this reader is registered. If it is not, register it before reading DSY files. It is located in the HWDIR\externalreaders\bin\$PLATFORM\plot directory. After registering the reader, you can read DSY files directly into HyperGraph.

HyperGraph hgthp Result Reader


Description	Supports
Reads PAM-CRASH and PAM-CRASH 2G THP binary files (time history files generated by the solver) into HyperGraph. Also reads ASCII files generated by exporting curves from PAMVIEW. hgthp can be run from the command prompt to convert THP files into Altair Binary Files (ABF files). The PAM-CRASH THP reader is enhanced to handle higher version result files. No ESI license is required to use this reader.	The PAM-CRASH and PAM-SAFE options. Solid Elements Only the first seven variables of Table A in the PAM-CRASH Notes Manual, Plot Output 5, (output qualifiers SXYZ and EPLE). Shell and Membrane Elements Only the first fourteen variables of Table A in the PAM-CRASH Notes Manual, Plot Output 7, (output qualifiers MXYZ to STRA). Beam and Bar Elements Only the first fourteen variables of Table A in the PAM-CRASH Notes Manual, Plot Output 13, (output qualifiers FAXI to RTN2). Results for nodal time histories, transmission sections, airbags, airbag chambers, airbag walls, materials, contacts, and rigid walls are also supported. A new data type, shell_user, is added to display the results for user-defined shell materials.

Usage

To run from the command prompt:

–hgthp thpfile outfile.

To run in HyperGraph:

By default this reader is registered. If not, register it before reading THP files. It is located in the HWDIR\externalreaders\bin\$PLATFORM\plot directory. After the reader is registered you can read THP files or PAM-CRASH ASCII files directly into HyperGraph.

HyperGraph erfh5 Result Reader

HyperGraph and HyperView uses same ERFH5 result reader to support ERF (HDF5) results.

HyperGraph reader supports Femzip ERF (HDF5) results, femzip library version 6.1.2019.

The PAM-CRASH ERF (HDF5) reader is enhanced to handle higher version result files.

PAM-CRASH ERF reader support ERF (HDF5) results that use modular input definition.

Entity pools are also used to handle duplicate IDs shared across different modules in the same model. These entities will be represented by their module IDs along with their parent entity module IDs.
