NACA 4412 study case

Hello 
I have some questions about the NACA 4412 case file provided in cfd support study cases:
1- how to set the simulation for other meshing (structured ones) that I did using block mesh please.
2- Trying to run the case without making any change gives this error. I tried to solve it many times without success. any suggestion on how to solve it especially for the solver related ones (rhomin....)
here the error message:

rhoSimpleFoam convergence

Have you got any advice or sample files (fvSolution, fvSchemes) for getting rhoSimpleFoam to converge please?


I'm running an aircraft case at Mach 2.0, using rhoSimpleFoam, with freestream BC in the far-field.

The whole solution becomes very oscillatory, even though initial convergence looks ok. I am using relaxation factors and limiters that have worked for me before.  I have used rhoSimpleFoam many times before for supersonic applications, but this time I'm having difficulty.

πŸ€– AI is making its way into our field of CAE, and it's moving at lightning speed! 🌐

AI for CAE

The question isn’t β€œif” but β€œhow soon”

CAE, or Computer-Aided Engineering (CFD, FEA, FSI, and optimization), is a field that utilizes computer software and tools to deliver the design, analysis, and optimization of engineering systems and components. This field plays a crucial role in industries such as automotive, aerospace, manufacturing, and civil engineering, enabling engineers to make informed decisions and improve the efficiency and reliability of their designs.


With recent developments, seeing how AI (Artificial Intelligence – here I mean rather Machine Learning but only calling it AI to make things easier) is disrupting field by field, everything seems that AI will disrupt the CAE field too. In my humble opinion, it’s just a matter of time and the only question is when (and how exactly) it happens rather than if it happens.


We’re just somewhere at the beginning and it’s even very difficult to say what is going on at the moment – not a mention that it’s impossible to predict what will happen in the future. However, there are a couple of things that we CAN say. 


The thing is, the usual CAE workflow involves a bunch of easy manual tasks and decisions based on data. And AI seems to be perfect for lending a hand with all of that.

πŸ” Centrifugal Pump CFD & FEA + FSI simulation: πŸ’¦πŸ”„πŸš€


πŸ” Centrifugal Pump CFD & FEA + FSI simulation: πŸ’¦πŸ”„πŸš€


Centrifugal pumps play a critical role in many industries, and optimizing their efficiency can result in significant cost savings. πŸ’°πŸ’‘

Computational fluid dynamics (CFD), finite element analysis (FEA), and fluid-structure interaction (FSI) simulations can be utilized to simulate the performance of a centrifugal pump and optimize its design. πŸ–₯οΈπŸ“ˆ

CFD simulations help understand the fluid flow inside the pump, identify areas of recirculation, and predict important performance metrics such as head, flow rate, and efficiency. πŸŒͺοΈπŸ’§

FEA simulations analyze the structural integrity of the pump, ensuring it can withstand the stresses and strains of operation. πŸ’ͺπŸ§ͺ

FSI simulations combine the results of CFD and FEA simulations to provide a more accurate representation of the pump's performance, accounting for the interaction between the fluid and the structure. πŸ”„πŸ”¬

At TCAE, we offer comprehensive CFD, FEA, and FSI simulation services for centrifugal pumps. Our simulations help optimize pump design, reduce energy consumption, and improve overall performance. πŸ’»πŸš€

By using simulations to optimize the design of a centrifugal pump, companies can save money on energy costs and increase the pump's lifespan. πŸ’°πŸ’‘

In conclusion, CFD, FEA, and FSI simulations are powerful tools for optimizing the design and performance of centrifugal pumps. TCAE provides comprehensive simulation services to help companies save money, reduce energy consumption, and improve operational efficiency. πŸ’¦πŸ’ͺπŸ’»

Unable to install and configure Openfoam-9 on RHEL-8

Hi Team,


Recently I am trying to install and configure Openfoam-9 source file on RHEL operating system. But I could not able to install it successfully. So I need your support to install this OpenFoam-9 on RHEL operating system. It is very urgent, so please if it possible to schedule a Zoom or WebEx meeting to fix this issue.


I have already installed these below listed OpenFoam version RHEL-7 and RHEL-8 OS and it is working fine.

OpenFoam-6 -> RHEL-7.9

OpenFoam-10 -> RHEL-8.9

OpenFoam-2306 -> RHEL-8.9
