Dear Sirs,

I want to export a francis turbine runner geomtery to TCAE Pareview... I get always an error

"Loading inputfile "C:\Users\lenovo\Documents\resources\geometry\ft27022023.tcae"...

Required keyword "1_solid-meshInput" with 1 entries is missing in the setup file.

No path to STL file for solid component 1

Inputfile "C:\Users\lenovo\Documents\resources\geometry\ft27022023.tcae" contains invalid settings.

Failed to import surface geometry file "C:\Users\lenovo\Documents\resources\geometry\". A path to .stl or .step file expected."

Mesh is set to cfd mesh only...

anyone to help me..

Best Regards

Hello everybody,

I try to model free convection inside vertical cylindrical container with elliptical bottom end. I cannot find how to calculate heat and mass fluxes (or flow rates) through horizontal plain, which divides elliptical and cylindrical parts. It is not a physical boundary, just a geometrical figure. For meshing I am using GMSH 4.8.4. Could someone help me please.

Hello everybody 

At the moment I am doing a heat radiation simulation with the viweFactor model in OpenFOAM 8. It is about modeling the solar radiation on a mirror and reflecting it to a plate, I am not using the solid domains but I am modeling only the air domain. My problem is that I don't know which are the files or directories that I need to model the radiation with the viewFaxctor model?

Could you help me with an example, so I can develop my case study?

Thanks

This category is focused on providing a public discussion, and guidance exclusively for the RWIND simulation environment. Specifically, the theory and strategies related to CFD methods.

RWIND is a software tool for simulating wind loads on buildings and other structures. It is a comprehensive tool that can be used to analyze the wind loads on a wide range of structures, including buildings, bridges, towers, and other structures. RWIND software also provides a user-friendly interface that allows users to easily input building geometry and wind data, as well as create and edit wind load cases. The results of the wind load calculations can be viewed and analyzed in various formats, including detailed reports, graphs, and 3D visualizations. It is used by engineers and designers to predict wind loads on a structure and check if it is designed to withstand those loads. It's a widely used tool by consultants and contractors for the design and construction of wind-sensitive structures like bridges, skyscrapers, towers, and more.

This category aims to enable discussion and support and enhance the users' knowledge and skills in using RWIND.

Computational Aeroacoustics (CAA) is a field of study that uses numerical methods to simulate and predict the generation, propagation, and effects of sound waves in a fluid flow. This category can include the analysis of noise generated by aircraft, wind turbines, and other machinery that operate in a fluid environment. The goal of this category CAA is to improve the understanding of the physical processes that lead to sound generation and to develop new technologies and design methods that can reduce noise emissions and improve overall performance. The discussion group is focused on the latest advancements, challenges, and future directions in the field of Computational Aeroacoustics.

This category is dedicated to Optimization in Engineering Simulations. We discuss here optimization methods, tools, and case studies. 

CFD (Computational Fluid Dynamics), FEA (Finite Element Analysis), and FSI (Fluid-Structure Interaction) simulations are used to analyze and predict the behavior of fluid flow, heat transfer, and structural mechanics in various engineering applications. Optimization is the process of finding the best solution to a problem by adjusting various input parameters. Optimization can be applied to CFD, FEA, and FSI simulations to improve the accuracy and efficiency of the simulation results. For example, optimization algorithms can be used to adjust mesh size, boundary conditions, and material properties to improve the accuracy of the simulation results, or to minimize the computational cost of the simulation.

Parametric optimization is a specific type of optimization in which the input parameters of a CFD, FEA, or FSI simulation are varied systematically to find the optimal solution. In parametric optimization, a set of input parameters is defined as the design variables, and a set of performance criteria is defined as the objective function. The optimization algorithm then searches for the combination of input parameters that minimizes or maximizes the objective function.

For example, in a CFD simulation of fluid flow through a pipe, the design variables might include the pipe diameter and the roughness of the pipe walls, while the objective function might be the pressure drop across the pipe. The optimization algorithm would then search for the combination of pipe diameter and roughness that minimizes the pressure drop.

Similarly, in an FEA simulation of a structure, the design variables might include the material properties and dimensions of the structure, while the objective function might be the stress or deflection of the structure. The optimization algorithm would then search for the combination of material properties and dimensions that minimizes the stress or deflection.

In an FSI simulation, the design variables are the parameters that affect the fluid and structure behavior, the objective function can be the displacement of the structure or pressure of the fluid.

Parametric optimization can be a powerful tool for designing and optimizing engineering systems, as it allows engineers to quickly and efficiently explore the design space and find the best solutions to their problems.
