FiberSim Reader

The FiberSim reader is supported for Nastran and OptiStruct user profiles.

Supported Entities

Entities supported by the FiberSim HDF5 reader.

Plies: Name, thickness, and fiber orientation information is directly read and mapped as a Ply entity. Ply architecture on each material is also mapped to the appropriate HyperMesh ply type. Unidirectional and core material architectures map directly. The woven type is mapped to a unidirectional-weave ply in HyperMesh and if E1 = E2, the material is dehomogenized to equivalent uni-directional material properties for the warp and weft tows. See the Ply Types documentation for details.
Date Map/Table: Data map with element set (ply shapes), material orientation angles (orient1 , orinet2 , draping corrections) thickness corrections, reference direction and normal information for each ply is preserved/mapped in the table entity, therefore each ply has a table associated with it. Nodes and elements are not created in the database from FiberSim triangulation data to define ply shapes. Instead, it preserves this information in a table so that when these plies are mapped (realized) on actual good mesh, HyperMesh uses this triangular information to define the ply boundary and extract the actual elements.
Laminates: One laminate per HDF5 component with all the ply sequence preserved as per layer_id value.
Materials: Material names and their mechanical properties are read and mapped to solver cards automatically depending on the user profile loaded while importing the model. Currently mechanical properties such as E1, E2, E3, G12, G13, G23, Alpha1, Alpha2 and Alpha_ref temperature are mapped to solver material attributes.
Rosette/Systems: All the system definitions available in the HDF5 file will be imported into one system collector. Currently HyperMesh does not preserve the ply and system relation.
