Dlubal Software competitors and assessment
Company assessmentDirect peers
- MIDAS (midas Gen / midas Civil): MIDAS provides structural analysis software for buildings, bridges, and civil structures, with particular strength in civil/infrastructure engineering that overlaps with Dlubal's bridge and large structural work.
- Trimble (Tekla Structures / Tekla Structural Designer): Tekla Structural Designer is a steel/concrete/timber BIM-integrated structural analysis offering that directly competes with RFEM/RSTAB for engineering firms that span BIM and analysis workflows.
- SCIA Engineer (Nemetschek Group): SCIA Engineer is a structural analysis and design software suite competing head-to-head with RFEM/RSTAB, serving structural engineers on steel, concrete, and timber projects across the same European and global customer base.
Broad incumbents
- ANSYS: ANSYS is a Tier-1 FEA platform competing with RFEM on general-purpose structural simulation, with much larger R&D and multi-physics depth; listed by Kings Research alongside Dlubal as a Top 10 FEA software company.
- Dassault Systèmes (SIMULIA): SIMULIA Abaqus competes at the higher end of FEA for structural and multi-physics simulation, co-listed with Dlubal in the Kings Research Top 10 and targeting overlapping structural and mechanical engineering buyers.
- Autodesk (Robot Structural Analysis / Revit): Autodesk bundles structural analysis (Robot Structural Analysis) inside its dominant BIM platform (Revit), making it the most important broad-incumbent competitor targeting Dlubal's structural-engineer customer base through BIM-centric workflows.
- Bentley Systems (STAAD.Pro / OpenTower): Bentley sells STAAD.Pro and tower/mast-focused structural analysis products, overlapping directly with RSTAB/RFEM while leveraging Bentley's broad infrastructure engineering portfolio and iTwin platform.
- Altair (HyperWorks / Inspire): Altair's HyperWorks/Inspire portfolio includes simulation tools for structural analysis and optimization, competing with Dlubal's RFEM and add-on modules on multi-material structural problems.
Emerging players
- SimScale: SimScale offers cloud-native FEA and CFD simulation with a SaaS delivery model, an emerging competitor to RFEM and RWIND 3 on the cloud- and subscription-based side of the same market.
- IDEA StatiCa: IDEA StatiCa focuses on steel and concrete connection/joint design (CBFEM-style), directly competing with Dlubal's RFEM Steel Joints add-on and CBFEM module for the same structural engineer persona.
