Force Prediction

FloEFD can be successfully used to analyze forces, including torque and pressure loads resulting from flow in or around a design.

Improve product reliability with concurrent CFD

Mentor Graphics’ concurrent CFD tool FloEFD, is the perfect analysis tool to simulate and predict forces such as torque and pressure loads resulting from flow in or around a design

Predict stress

Forces and pressure loads simulated using FloEFD can be used for subsequent structural analysis such as stress and deformation analysis, thermal stress predictions, etc. For this purpose it is very easy to transfer FloEFD results as load conditions into leading FEM software tools.

Investigate with ease, ‘what-if’ scenarios within your native CAD environment

FloEFD is able to bring the power of 3D analyses to any design engineer with MCAD experience. The software’s unique ability to integrate with a user’s native CAD system means the engineer can concentrate on his/her designs, allowing them to quickly explore ‘what-if’ scenarios in a virtual environment in the pursuit of a products full potential.

Success Stories

Aerodynamic Coefficients

Aerodynamic Coefficients

Prediction of aerodynamic coefficients of objects is one of the classic applications of flow simulation. Besides the ability to simulate airflow over the entire range of engineering-relevant Reynolds numbers from laminar and transitional to subsonic, supersonic and even hypersonic flows, FloEFD offers a wide range of additional physical models for characterization of the aerodynamic behavior of a design.

This includes a unique automatic laminar/turbulent modeling approach, an innovative model to simulate near-wall physics in a very efficient way as well as a complete suite of visualization and numerical post-processing functions providing a comprehensive insight into the 3-dimensional flow field and easy determination of aerodynamic coefficients and derived parameters.

Operational Forces for Valves

Operational Forces for Valves

Dimensioning of valves under a given cost, reliability and lifetime requirements is often a challenge for engineers, especially if fluids with complex properties or special physical effects are involved. To address this, FloEFD offers for example, a full two-phase implementation of steam for a very accurate virtual testing of devices with steam under various physical and environment conditions.

Additionally, FloEFD comes with a complete phase-change cavitation model to consider the effects of cavitational flow on forces acting on valve parts. Moreover, FloEFD's integrated parametric study tool allows a user to automatically determine the flow rate of check valves under a defined pressure load, calculating the balance of the flow-force defined valve opening acting against the spring.

Wind Loads

Wind Loads on Buildings, Bridges

Analyzing upfront, potential wind loads on structures such as buildings, bridges, antennas, etc, are one of the major factors often defining the requirements for dimensioning and testing of those structures for stress, deformation, and dynamic response. In order to get realistic aerodynamic loads for subsequent structural analyses a simulation of various wind load conditions is essential.

FloEFD has specific built-in functionality to address such challenges, these include a comprehensive set of non-Newtonian liquid models, flexible wall slip coefficient adjustment, handling of very complex CAD geometry and more.

Flow-Induced Loads

Flow-Induced Loads for Stress and Deformation Analysis

Computed flow-induced loads using concurrent FloEFD, can easily be transferred to leading FEM structural analysis software either using ready-to-run FEM bridges such as Pro/ENGINEER Mechanica bridge, or by employing FloEFD's powerful Application Programming Interface to access and transfer FloEFD.

Temperature Distribution

Temperature Distribution for Thermal Stress Analysis

Computed temperature fields using concurrent FloEFD can easily be transferred to leading FEM structural analysis software, either using ready-to-run FEM bridges such as Pro/ENGINEER Mechanica bridge, or by employing FloEFD's powerful Application Programming Interface to access and transfer FloEFD result data from any point in the flow domain to the corresponding location in the FEM stress analysis model.

Cleaning Systems

Cleaning Systems

Automatic cleaning systems often employ specifically designed local flow patterns to generate the necessary level of near-wall shear stress for removing unwanted material accumulated at the wall, in gaps, etc.

Concurrent FloEFD is used to simulate the flow patterns in complex designs, and to calculate and visualize the resulting shear stresses in the near wall regions. This helps engineers to understand the local flow situation and to improve the design to meet all criteria for a safe and reliable cleaning process.

Torque Prediction

Torque Prediction

Predicting torque as a fundamental reaction force to flow is very important for many designs such as the operation of valves (opening/closing) and the dimensioning of the corresponding drives, the torque acting on rotating parts such as impellers, and many more.

Concurrent FloEFD's built in customizable parameter concept, allows a user to directly access torque values and even allows users to define their own, derived or non-dimensional parameters for easy design validation.
