Download ROHR2 34.0

ROHR2

ROHR2 is a leading European CAE software for static and dynamic pipe stress analysis, widely used in power plants, chemical industries, and nuclear engineering. The latest version, ROHR2 35.0 (released May 18, 2026), adds enhanced FEM modules, CAD/CAE integration, and improved dynamic load handling.

🔑 Core Capabilities

Static Analysis
- Handles linear and nonlinear boundary conditions (friction, support gaps, uplift).
- Supports first and second order theory for load combinations.
- Automatic load case superposition per selected stress code.
Dynamic Analysis
- Eigenvalue and mode shape calculations.
- Modal response and direct integration methods (e.g., fluid hammer).
- Earthquake analysis via Time-History method.
Code Compliance
- Supports ASME, EN, ISO 14692, KTA, CODETI, RCCM, DVS 2210.
- Compares actual vs allowable stresses with detailed reports.
Specialized Modules
- ROHR2fesu: Finite Element analysis of substructures.
- ROHR2iso: Automatic piping isometries.
- ROHR2flange: Flange calculations (EN 1591-1, ASME VIII).
- ROHR2nozzle: Nozzle load analysis (API 610, 617, 661, DIN EN ISO standards).
- Internal Pressure Analysis: For piping components under pressure.
