I’m familiar with the experimental methods to determine the damping ratio of a material, but I’m wondering if ther...

I would like to report an issues with SnappyHexMesh when running with OpenFoam v2306. I'm currently try to run SnappyHexMesh with high mesh number structure in HPC cloud environment. Unfortunately, the process of "snappyhexmesh -overwrite" stuck and hanging at refinement phase with message "Found...

This is more like an open question than a fully formed topic with both question and answer.

I am running an incompressible laminar flow simulation with the pimpleFoam solver. It has two openings on one side (n1 and n2) and one on the other (n3). I have set up the pressure boundary conditions so that the flow is driven primarily by the pressure applied at n3. The flow should be...

Hello, I am very new to CFD and simulations, I am trying to simulate the power output of a kaplan hydro turbine. I have made the geometry, but when I try to mesh it, after 15 minutes it fails. Is there any function in TCAE that I can use to check the mesh, I think it might not be water tight, but I don't know where. Also, the setup check passes without errors.

If you need a...

Hello,

I tried to run the benchmark cases NACA0012 and now I am at TCAE module. I have noticed that the running time of TCAE is long and I want to accelerate it but I haven't found places to set the number of processors. Is  that means the module cannot be computed in parallel? By the way, no my CPU utilization is low bu...

Hello, I tried to run the benchmarks case DJI9450 that I downloaded from CFD SUPPORT. But the  CFD calculation failed after 100 hours running and it showns that "Application redDyMsolver failed" . And there was nothing in the error log. I haven't change anything except the number of processor. Would it be OK if I run it again?

Thanks for your help.

Hi there

I don't know if tihs would help but I was wondering if anyone can help me to apply a "opening" condition in OpenFoam, in the picture you can see almost a square, and what I have in my problem is that from a little part of the left side I have an inlet and a part of the top part I have an outlet. Also I know that my outlet takes twice the flow that goes in from the inlet, and in t...

Hello everyone,


I have questions about the calculation of circumferential angles circA by TCAE.


I have understood that, if a surface is oriented in the radial direction, circA on this surface will be the angle between the tangent and the velocity in the radial/tangential plane. According to graphical representation of the manual, circA shoud be positiv when the...

Hey, I was wondering if anyone could help me to understand the different solvers OpenFoam has for different purposes, I thing I have understood icoFoam and simpleFoam but if anyone could help me to know when and how to use the potentialFoam and all of them I would appreciate it a lot.

Thanks in advance for the help 

Hi everyone,

I am thinking about using the TMESH module to mesh my geometries via SnappyHexMesh and I was wondering if you have any recommendations (regarding the values and significations of the different parameters for example)? Any advice or material would be really helpful.

Thank you very much and have a nice day,
Alex

What is your recommended tool flow from Solidworks to TCAE that preserves surface names (inlet, outlet, walls etc) ?

My understanding is that unfortunately Solidworks does not preserve surface names when exporting the model as...
