For this LB simulation, how many cores are used and how long does it take? Furthermore just wanting to confirm, is the motion of the blade is externally prescribed or EOMs are being solved here or the blades are already deformable?
Thanks for your interest! As stated in the description this simulation used a single accelerated node on HoreKa Teal consisting of four Nvidia H100 GPUs. It took around 8 hours, the bottleneck was actually the Paraview visualization afterwards. All four rotors where two-day coupled, i.e. the rotation was not prescribed but resulted of the fluid flow acting on them. However, the blades are not yet deformable.
can we make new designs in Solidworks and export it to openlb codes? How to export it, do I have to just put it simply in the folder or I have to make changes in the code also?

@@kummerlaender in the future for FSI simulation, is there any plan to include the solid mechanics solver using LBM instead of FEM?
@@bryangohmppac6417 yes
who puts these together and where can I see the code? I need serious help with getting my simulations up and running. please help!
Have a look at www.openlb.net -- www.openlb.net/consortium/

Usually yu start with a surface mesh (in stl format) a good intruduction into the code offers the spring school
