Why Choose Simplex?
Cloud Based
Simplex is cloud based with a shared online file management system. It is accessible from anywhere, from any platform. No download, no installation.
One Platform
Avoid jumping between multiple platforms. Simplex brings all your 2D calculations together in one site, making your workflow faster and easier to manage.
Floating Licenses
Simplex uses cloud licensing that still is floating – with no seat limit. Administrate and add people inside the StruSoft Portal.
Online SDK
Access the Simplex SDK online, connect with FEM-Design or build your bespoke workflows using our proven backend calculations.

CENTER
Simplex Center is the main file management system and navigation hub in the Simplex Suite, where you can organise, sort and access all your projects and files.
- Project and file management: Organise, label and sort your files in an intuitive way.
- Multi-print*: Print multiple files and merge them automatically into a single PDF.
- Share and collaborate*: Share files with colleagues, collaborate easily, and access your projects from anywhere. *New features in next release
BEAM
Simplex Beam is your go-to structural design app for steel, timber and concrete beams. Quick and transparent results, all according to Eurocode standards.
- Load combination generator: Automatically generate all relevant load combinations to streamline the design process and reduce manual errors.
- Fire design: Perform fire analysis to ensure the design meets fire safety requirements for timber, steel and concrete.
- Optimised design: Automatically identify the most efficient profile for steel and timber sections, and design the reinforcement layout for concrete beams automatically.
FOUNDATION
With Simplex Foundation, you can analyse and design pad and strip foundations, including settlement analysis and concrete design, in accordance with Eurocode.
- Settlement calculations: Define your soil strata and obtain more detailed settlement calculations for pad and strip foundations.
- Automatic design: Automatically generate optimised foundation geometry and reinforcement to save both time and material.
- Interoperability: Export reaction forces from FEM-Design to Simplex Foundation, or use our Grasshopper toolbox for foundation design.
COLUMN
Design concrete, steel and timber columns with Simplex Column. Apply imperfections, eccentricities, and carry out 1st or 2nd order analysis and design.
- Easy load definition: Apply loads and calculate their effects, define internal forces, or combine both approaches.
- Flexible geometry: Model columns spanning multiple storeys. Apply local eccentricity offsets and define load positions.
- Second-order analysis: Carry out a more advanced second-order analysis in accordance with the general method for concrete.
FRAME
Simplex Frame is a modern, easy-to-use 2D frame design software for steel, timber and concrete frame structures, in accordance with Eurocode.
- Quick and easy modelling: Use modern tools to build your model on the canvas, or switch to the table view for a fast overview and easy model checking.
- Load generators: Generate snow, wind and variable loads using built-in macros.
- Powerful analysis options: Run first- and second-order analysis, eigenfrequency and stability analysis, and fire design for steel, timber and concrete. Include tension-only and compression-only elements. Consider shear deformations using the Timoshenko beam theory.
RETAINING WALL
