EngiLab Beam.2D Lite (now widely known as EngiLab Frame.2D Lite) is a structural analysis software designed for the linear static analysis of plane (2D) frames, continuous beams, and trusses. It operates on the Finite Element Method (FEM) and uses a 3-Degrees of Freedom (DOFs) per node framework.
The Lite edition is completely free of charge for non-profit, personal, academic, or educational use. Core Analysis Capabilities
The software focuses on calculating structural responses under static loads and provides clear graphical feedback:
Calculated Metrics: Node displacements, support reactions, and element end forces.
Visual Diagrams: Automatically generates Free Body Diagrams, Model Deformation, Axial Force, Shear Force, and Bending Moment (NVM) Diagrams.
Load Types: Supports nodal loads, uniformly or linearly varying loads (trapezoidal/triangular) along elements, and body acceleration loads like gravity/self-weight.
Structural Flexibility: Accommodates any type of constraints (fixed, pinned), springs, and rotation releases (hinges) at element ends. Key Features
Intuitive Graphical Interface: Features a modern, user-friendly UI for both pre-processing (modeling) and post-processing (results viewing) with seamless zoom and pan support.
Section Properties Calculator: Includes a built-in tool to compute the property values for standard structural cross-sections.
Unit Compatibility: Completely compatible with any consistent unit system, including Metric, SI, and US Imperial customary units.
Equilibrium Validation: Automatically cross-checks results by verifying that the global and individual element forces sum to zero.
CAD Integration: Allows users to import DXF drawings directly to use as analysis models. Lite vs. Pro Edition Differences
The Lite version is fully featured but introduces capacity limitations to differentiate it from the commercial Pro version: EngiLab Frame.2D 2022
