ROHR2
CAE System for Static and Dynamic Analysis of Complex Piping and Skeletal Structures
ROHR2 is the worldwide used standard tool for Pipe static and Structural framework analysis, covering a variety of specifications like ASME, EN, CODETI, STOOMWEZEN D1101, KTA, FDBR and ISO 14692.
The software environment can be supplemented by a range of programs enhancing the engineer’s daily job, as there are FE- analysis, isometric capabilities and interfaces covering the leading CAD/CAE systems.
ROHR2 is used by generations of engineers doing their jobs in power plants, nuclear power engineering, chemical industry, gas piping and technical control authorities.

Program system ROHR2 - Optional modules and interfaces
The program system ROHR2 is equipped by a range of additional features enhancing the engineer’s daily job, as there are FEM analysis (ROHR2FESU), isometric capabilities (ROHR2ISO) and a wide range of interfaces covering the leading CAD/CAE systems.
ROHR2 Interfaces
Communication with CAD/CAE software:
AVEVA PDMS, CADISON, INTERGRAPH PDS/ SMARTPLANT, MPDS4, HICADnext, CII, SINETZ, AUTOCAD via ALIAS PCF/ISOGEN, AUTOPLANT and othersTasks of ROHR2
The main tasks of ROHR2 are component analysis, construction and structure analysis of complex piping systems.
The static analysis includes the analysis of any loads and load combinations according to first and second order theory for linear and nonlinear boun¬dary conditions (friction, gap of supports, support uplift) and coupling conditions (nonlinear regulation powers of expansion joints).The dynamic analysis includes the calculation of eigen values and mode shapes and their analysis by means of different modal response methods (e.g. analysis of fluid hammer forces).
The earthquake analysis bases on the Time - History - Method.
An efficient superposition module enables a versatile selection and combination of static and dynamic results as well as the generation of extreme values for loads on supports, components and nozzles.
Stress analyses of pipe components can be done by a variety of specifications like ASME, EN, CODETI, STOOMWEZEN D1101, KTA, FDBR und ISO 14692.
ROHR2 creates the load case superposition and the equations automatically according to the selected stress specification.
ROHR2 compares existing and allowable stresses. The results will be documented in lists and graphic representations
The software is equipped by a range of additional features enhancing the engineer’s daily job:
- a wide range of interfaces covering the leading CAD/CAE systems,
- ROHR2fesu FEM analysis,
- ROHR2iso - isometric capabilities
- ROHR2stoss - Structural Analysis with Dynamic Loads using Direct Integration
