The .h3d file is a compressed binary file, containing both model and result data. It can be used to post-process results in Altair HyperView or when using the Altair HyperView Player.
The .h3d file is created when the H3D format is chosen (see I/O options FORMAT and OUTPUT), and an analysis only run is performed (meaning no design variables or design spaces are defined in the model); the I/O option ANALYSIS is present; or the command line switch -analysis is used (see Options for Running OptiStruct).
The .h3d file contains node and element definitions in addition to the following results:
Result |
Description |
|
Acceleration |
Acceleration results from frequency response, transient response, and multi-body dynamics analyses. Output is controlled by the I/O option ACCELERATION. |
|
Composite ply strain |
Ply strain results for composite materials from static analyses. Output is controlled by the I/O option STRAIN and by the SOUTi field on the PCOMP definition. |
|
Composite ply stress |
Ply stress results for composite materials from static and analyses. Output is controlled by the I/O option STRESS and by the SOUTi field on the PCOMP definition. |
|
Composite failure indices |
Failure indices for composite materials from static analyses. Output is controlled by the I/O option STRESS, by the SOUTi, SB and FT fields on the PCOMP definition and by the related fields on the relevant material definition (see MAT1, MAT2, MAT8). |
|
Density |
Density results from topology optimizations. Output is controlled by the I/O option DENSITY. |
|
Displacement |
Displacement results from static, frequency response, transient response, and multi-body dynamics analyses. Output is controlled by the I/O option DISPLACEMENT. |

|
Stress |
Stress results from static, frequency response, transient response, and multi-body dynamics analyses. Output is controlled by the I/O option STRESS (or ELSTRESS). |
|
Thickness |
Thickness results from size and topology optimizations. Output is controlled by the I/O option THICKNESS. |
|
Velocity |
Velocity results from frequency response, transient response, and multi-body dynamics analyses. Output is controlled by the I/O option VELOCITY. |
Grid point stresses are output for the entire model and for each individual component. This allows grid point stresses to be accurately obtained at the interface of two components referencing different material definitions.
For dynamic analyses like frequency response, transient response, and multi-body dynamics, it is recommended that sets be used to reduce the amount of model and results output data. The output file can become very large since results are output for each frequency or time step.
