Thank you so much! With this way, can I compile any example of CGAL, for example, a of 3D convex hull?

Hi, i have installed openGL and libtbb2 on WSL2, but when i run the command './salome ' , it shows the error that " No module named ' salomeContextUtils' ". Please forgive this fool problem:)

Hello ! Thanks for sharing this. What would be the work around to import a .ply file containing multiple cylinders into FreeFEM ?

非常感谢您在这方便作的工作！ Very good video,it helped me solve many problems.

blessings your way

and another question that all mixed finite element are capable to apply using freefem

is there any way to use some sort of SOFTWARE AS INTERFACE except notepad++

the video is very interesting and I always follow it. is there a tutorial on how to make meshing on a helical pipe using hexahedral? previously I have followed your video using tetrahedral

very nice tutorial, can you make a video how to show the colume of water passing over an object? or maybe you can write the proccesses here under comments. tnx again

Sir I was using uniform velocity and setSlip boundary in Cylinder3d code of OpenLB with a new stl file having geometry extended at Y axis. The simulation runs well at resolution N = 10 but at higher resolution the simulation gets killed. Is there any solution to that. The error message is given below: [prepareGeometry] Prepare Geometry ...

Your explanation covers concepts that anyone with a background in LBM and a quick 10-minute read of the OpenLB documentation would understand. I watched this video hoping for more specific details that I could apply to my real projects. Unfortunately, it didn't meet my expectations. Nevertheless, I wish you good luck.

Hi, Can you build a model of closed-loop pulsating heat pipe ?.

Hi. Thanks for your videos. Can you please make tutorial on how to extend LiGGGHTS DEM Library for simulating magnetic and electrostatic force.

Hi and thanks for the great video. After following your guide, i can run paraview only by clicking on the executable "paraview" file in the bin folder. however, when i try to run the software in the terminal using "paraview" command i get this: Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway. ( 1.627s) [paraview ] VisRTXBackend.cxx:42 WARN| VisRTX Error: Unsupported device and the software doesn't start. what is the reason?

Thanks!

Thanks! Hope you're still familiar with this, I've been getting some issues while applying the Particle Tracer filter. Paraview just decides to crash. The only difference I have is that my files are *.VTK. Any idea what might be causing this? Awesome tutorial!

I wanted to install MPI and MANYBODY package by default but it's not working. It's asking for ADIOS2 and I install that and then ADIOS2 doesn't install with MPI and because it doesn't do that, lammps MPI cannot install. total disaster.

sir can i get your mail id

what terminal you used to run this ?

Thanks a lot. It is really helpful for my research

Great explanation sir, Thank you so much. Sir can you also explain how to solve semidiscrete galerkin in freefem.

Mine is asking for a password. What do I do?

Amazing tutorials! Thank you!

This video is very nice and easy to understand. It helps me a lot. Thx

This was very useful. Thank you!

Thank you for the detailed video. How do we do it if the Lagrangian files are saved as VTK files?

First, you take over 9 minutes to get to the subject matter title of your video (moving rotating) then you don't show how to activate the Animation Keyframes dialog. Poorly done.

while opening the paraview from terminal after following the steps in the video it's showing the permission is denied

Should your title have better been "...for exporting it to other programs..." ?

Sir can you please tell me how to calculate the Element numbers and the Grid point number from the OpenLB codes for example from Cylinder2D? As in Ansys we can find the Element number or Grid number directly but I didn’t find any such thing in OpenLB codes. Such as for Cylinder2D code I have estimated like this: Identify the grid resolution: The resolution N is defined as 200. The lattice length L is defined as 0.1/N. L = 0.1 / 200 = 0.0005 The length of the domain in the x-direction (lengthX) is 2.2. The length of the domain in the y-direction (lengthY) is 2.0. The number of grid points in the x-direction Nx = lengthX / L. The number of grid points in the y-direction Ny = lengthY / L. So, Nx = 2.2 / 0.0005 = 4400 Ny = 2 / 0.0005 = 4000 Total Grid Points = Nx * Ny = 4400 * 4000 = 17,600,000 Is it correct? Please help. @TuxRiders

Did you test the performance in these two programs? Is there any advantage in execution times of any of them?

there is also an open source package called LBPM, if you are interested and convenient, can you explain how to install and use it ?

hello I use your technique to install Salome but it open just 67 percent and go back . I don't have any error

CMake Error at /opt/homebrew/Cellar/cmake/3.29.3/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message): Could NOT find OpenMP_CXX (missing: OpenMP_CXX_FLAGS OpenMP_CXX_LIB_NAMES) Call Stack (most recent call first): /opt/homebrew/Cellar/cmake/3.29.3/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:600 (_FPHSA_FAILURE_MESSAGE) /opt/homebrew/Cellar/cmake/3.29.3/share/cmake/Modules/FindOpenMP.cmake:581 (find_package_handle_standard_args) CMakeLists.txt:424 (find_package) i am having this error , how to resolve this

In this video you mention you are pressing m to display the grid. Is this a custom key/function. I am using Windows 11 and I don't have this function. Question: Is this discussed in the manual?

I really thank you for the explanation of this helpful tool. I still could not figure out the units of the Single-phase permeability obtained from this model. Is it in mD or D?

What a wonderful course! 🤩

Many thanks for your excellent work. Do you know a playlist of similar quality like yours for electromagnetic wave problems? I am no scientist but I look for a method to induce suitable back-mutations since 30 years. MoFEM seems to be useful. The main sentence is found in Tiplers physics that the particles that form are determined by wavepackages. Now I need solvers that allow to calculate back from spektrums to wavepackages. Has someone an idea or resources for that task? Thank you.

Hi, great vid! Do you know how can I calculate the determinant of a matrix?

If I understand it correctly, this builds Paraview but does not copy it to /usr/local/bin (and libraries to /usr/local/lib) right? To do that after the build completes, can I just run “sudo ninja install” to copy the built targets and libraries to these folders?

Is it normal to have a big overhead when running with MPI?

Many, many thanks for your courses. Without them, it would be impossible for me to learn the necessary math for a heart-project I would like to work on. I wish you the reward you deserve and millions of followers. 😊😊😊👍👍👍

Thank you so much. Just what I ever wanted to know. 😊😊😊👍👍👍

Danke! Danke! Danke! So bekommt man wenigstens eine Idee, was man tun könnte, wenn etwas nicht funktioniert. Klasse Videos!😊😊😊👍👍👍 Solche Erklärungen sind unglaublich nützlich. Auch in Kombination mit den AI-Tools, besonders den in Edge integrierten. Ersparen mir viele, viele Stunden in Foren, wo einen "Experten" höchstens blöd anmachen. Sorry - das werden Linux-Fans nicht verstehen, aber ich habe halt ganz schlechte Erfahrungen mit Foren und sehr gute mit AI.

Many thanks for these videos. I have a Windows 11 notebook and would like to follow your course. Is it possible to use the WSL 2 for ubuntu as virtual machine? Thank you for an answer.

Nice tutorial. But in newer versions (I use 0.21.2) I got an error when tried to apply the sweep. As I understood it requires to use "Shape Binder". At least with it worked for me. I followed the next steps: 1. With the Body active, select the helix path 2. Click "Create shape binder" icon and then OK 3. Hide original Helix 4. Use shape binder as a path

i try to convert the mesh to openfoam format but the boundary conditions are not implemented what should i do? i use meshtofoam command

I was hoping for some description and explanation of the code and its creation. This seemed to me to be completely useless, everyone can see this for himself what he was explaining. I don't know how it was supposed to help.

Hi, how to open "Animation View" in Paraview 5.12.0? I can't find it in "View"

Thank You for the efforts!
