You can show and hide elements, select elements and view results by group. User-defined beam sections Design your own beam cross-sections. Strand7 renders these in 3D for both pre-processing and post-processing, so you can create sections of arbitrary shape and immediately view them in the graphical editor. Verification tools Strand7 offers many mesh verification tools, like free-edge display.
You can contour many quantities, including aspect ratio, volume and applied pressure and temperature. General equation input Enter numbers as mathematical expressions. For example, you can assign node forces and plate pressures as functions of position. Undo and redo Strand7 offers a powerful unlimited undo capability. You can undo all modelling changes, no matter how complex or how many entities are affected. A redo function lets you reverse the previous undo. Automatic mesh generation Strand7 includes automatic mesh generation tools, working directly from geometry.
You can automatically generate 4-node and 8-node plates from 2D regions, and 4-node and node tetrahedra from 3D regions. Strand7 provides powerful geometry input tools for the automatic mesher. And to ensure you can generate a good quality mesh, Strand7 includes a suite of geometry cleaning, healing and defeaturing tools. User-defined coordinate systems Define your own coordinate systems, which can be rectangular, cylindrical, spherical or toroidal. Local coordinate systems can greatly simplify model-building and results extraction.
Plate thickness display Strand7 can render plate element thicknesses. This lets you clearly visualise the relative thickness of each plate, and helps you check for errors. You can easily contour results such as stresses on both plate surfaces simultaneously.
Sub-modelling Sub-modelling allows you to extract parts of a model and save them as separate files, with boundary displacement conditions automatically enforced as constraints. This lets you perform local mesh grading without having to re-solve the entire model.
Multiple freedom cases You can generate results for multiple sets of freedom conditions in a single model. Investigating results Solvers Strand7 includes the following solvers: Linear static Natural frequency Buckling Nonlinear static Linear and nonlinear transient dynamic Spectral and harmonic response Linear and nonlinear steady-state heat transfer Linear and nonlinear transient heat transfer Strand7 also provides the following data: Bill of materials for each group or sets of groups Inertia properties for each group or sets of groups Cutting planes You can specify arbitrary cutting planes in brick models, and view stress contours on these planes.
Load case combinations You can create a virtually unlimited number of load case combinations. Change these combinations at any time without having to re-solve the model. Searching Use searching to locate certain result values, or results exceeding a certain value. Result contours Strand7 helps ensure you detect all stress concentrations. You can contour stress that has been: averaged, not averaged, averaged only across elements with the same material, and averaged only across elements in the same plane for plate elements.
Enveloping For problems with multiple load cases, or transient problems with many time steps, you can display the envelope of maximum results over every load case or time step. Listings and reporting List, sort, filter and print result data in report format. You can filter results by group and property, and view results for only those entities selected in the graphical editor.
For more detail, request plate and brick results at nodes and Gauss points, and beam results at many positions along each beam. XY plots You can generate an XY plot of virtually any result parameter between two points on the model. Simply click on two nodes to specify the desired path. Material models supported by Strand7 include: Isotropic Orthotropic Anisotropic Laminate Rubber Soil User-defined To define nonlinear material behaviour, you can specify stress vs strain, force vs displacement, moment vs curvature and moment vs rotation tables.
It is normally used as a getting started guide. The Strand7 Verification Manual contains hundreds of fully documented problems, complete with reference solutions and comparisons with Strand7 solutions.
The actual model files are also distributed as part of the Strand7 installation for user reference and quality assurance reasons. Data files. The entire Strand7 data file is stored in a single. Strand7 is highly user-configurable.
