Straus7 features a fully integrated graphical pre-processor. Engineers can construct models directly within the interface or import geometry from CAD systems (such as AutoCAD, SolidWorks, or Revit).

At its core, Straus7 solves the fundamental equations of structural mechanics. It takes a complex geometry, breaks it down into a mesh of finite elements (beams, plates, bricks), applies loads and boundary conditions, and calculates the resulting stresses, strains, and displacements. Straus7 features a fully integrated graphical pre-processor
For small to medium engineering firms, Straus 7 software offers the best "power-to-price" ratio. It lacks some high-end multiphysics (e.g., CFD coupling), but for structural mechanics, it competes directly with top-tier software. It takes a complex geometry, breaks it down
Straus7 is a comprehensive finite element analysis (FEA) software package designed for structural simulation. Developed to solve linear and non-linear problems across various engineering disciplines, it provides a visual environment where engineers can model, analyze, and verify their designs.
: The software is typically issued as an MSI package. Running the installer will automatically uninstall previous minor versions (e.g., R3.1.x) but can coexist with major older versions like R2.4.x.
Buckling analysis of a composite stiffened panel under compression. Method: Straus 7 linear buckling + non-linear post-buckling. Result: Good correlation with NASTRAN and test data (error < 8%). Advantage: Fast setup of ply layups and buckling mode extraction.
