Strand7 Unique Features

The very unique set of powerful capabilities that Strand7 provides makes it a superior tool for a wide variety of applications. Contact BAI for a full list and detailed descriptions of these features. Here are brief descriptions of a few of them.

Beam Sections  
Standard beam sections. Commonly used sections may be created easily by using the standard section generator.

Library beam sections. Standard section libraries from numerous countries are also available in the section libraries.

Mirror Beam Sections. Selecting the mirror tab when editing a beam section presents the option of mirroring the geometry to generate the composite sections. Mirroring is available for all shapes except BXS and circular sections in 12 configurations and can be viewed in the property window for easy identification.

Arbitrary user-defined beam sections. Design your own beam cross-sections. Strand7 renders these in 3D for both preprocessing and post-processing, so you can create sections of arbitrary shape and immediately view them in the graphical editor. Strand7's section calculator generates a true torsion constant whenever you create a user-defined section.
Laminated Composites  
Strand7 may be used for the analysis of laminated composites via dedicated pre processing, solver and post processing modules. Both symmetric and unsymmetric laminated composites are supported.

Easily create a laminate. Creating laminate stacks in Strand7 is simple with the Laminate Composites module. Define each ply according to material properties and thickness, then use the Laminate Lay Up tool to build the stack including ply orientation angles. Engineering properties and the laminate stiffness matrix are automatically generated as the stack is defined or modified.
View and Manipulate Ply Axes. Ply axes for directional composites on a structural model can be viewed and changed at will. Use the Drape tool to align the composite according to a master element. Alternatively, align axes by projecting to any coordinate system.
Strand7's post-processing environment allows you to contour composites according to a specified ply stress or reserve factor. Alternatively, the maximum or minimum ply stress or reserve factor can be contoured.
Submodelling  
Sub-modelling. Submodelling allows you to extract parts of a model and save them as separate files, with boundary displacement conditions automatically enforced as restraints. This lets you perform local mesh grading without having to re-solve the entire model.

Step 1. Create and solve a coarse mesh.

Step 2. Extract the sub-model and verify that the results are the same as the original full model.

Step 3. Globally refine the model and re-solve to obtain a better solution. Boundary conditions are automatically interpolated by the automatic mesh subdivision tools.
