What specs should I look for in a new laptop for CFD learning?
Previously where I worked in R&D, we used to deal with quite large elements and we ran those cases on workstations sometimes with 48 cores...etc I'm looking to buy a new personal laptop and I'm not sure what specs should I care for for my CFD learning, whether on OpenFOAM or other commercial software. Should I care for the graphics card as much as RAM, Storage and Processor? What about number of cores/threads...Any source I can read on that or experience?

It depends a lot on the CFD applications. To learn and use a bit of OpenFOAM: - RAM DDR5 minimum 16Gb. 32Gb is desired. - Processor: as fast as your budget allows. However, the number of cores doesn't matter because typically, it's not efficient to use more than 4 cores — it has to do with the RAM bandwidth limitation. - GPU: not relevant for OpenFOAM or ParaView. Get a regular one. - Discs: At least 1Tb. 2Tb is better. - Good fans/ventilation. If you intend to install OpenFOAM in a WSL in windows, go for 32Gb of RAM, 2Tb of SSD, and a processor with 8 cores/16 threads. Have fun!

Maybe some GPU may accelerate the calculations, depends on the software. Check with the sellers.

Ubuntu is the most unforgivable OS for work
I use ubuntu for preprocessing and openfoam and with canonical’s latest update it has: Destroyed my resolution settings Wrecked CUDA Made blender useless. If you want a suitable linux distribution do not waste your time, use arch linux.

I have been using openfoam and paraview on Ubuntu for 10 years every day without any problems.

@Suhaib Yasin, do you know that there are LTS versions of Blender? And of Ubuntu? You can keep your workflow for several years without having to make significant changes.
