ROHR2. ROHR2 is a CAE system for pipe stress analysis from SIGMA Ingenieurgesellschaft mbH, based in Unna, Germany. The software performs both static and dynamic analysis of complex piping and skeletal structures, and runs on Microsoft Windows platform. [1][2] ROHR2 software comes with built-in industry standard stress codes; such as ASME B31.1 ...
OLGA is a modelling tool for transportation of oil, natural gas and water in the same pipeline, so-called multiphase transportation. The name is short for "oil and gas simulator". The main challenge with multiphase fluid flow is the formation of slugs (plugs of oil and water) in the pipelines, which causes large problems at the receiving end at ...
Stress–strain analysis (or stress analysis) is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other ...
NASTRAN is a finite element analysis (FEA) program that was originally developed for NASA in the late 1960s under United States government funding for the aerospace industry. The MacNeal-Schwendler Corporation (MSC) was one of the principal and original developers of the publicly available NASTRAN code. [1][2] NASTRAN source code is integrated ...
Process piping and power piping are typically checked by pipe stress engineers to verify that the routing, nozzle loads, hangers, and supports are properly placed and selected such that allowable pipe stress is not exceeded under different loads such as sustained loads, operating loads, pressure testing loads, etc., as stipulated by the ASME B31, EN 13480, GOST 32388, RD 10-249 or any other ...
Pipe network analysis. In fluid dynamics, pipe network analysis is the analysis of the fluid flow through a hydraulics network, containing several or many interconnected branches. The aim is to determine the flow rates and pressure drops in the individual sections of the network. This is a common problem in hydraulic design.
t. e. Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid (liquids and gases) with surfaces ...
GOMA is an open-source, parallel, and scalable multiphysics software package for modeling and simulation of real-life physical processes, with a basis in computational fluid dynamics for problems with evolving geometry. A generic finite element library written in C++ with interfaces for Python, Matlab and Scilab.
