Adsorption Energy of Water on 2D Periodic hBN Monolayer using TURBOMOLE and TmoleX [TUTORIAL] YouTube video by Phys Whiz

Hi #compchem #compchemsky
Tired of costly 2D materials simulations in VASP?
Huge vacuum + dipole corrections = unnecessary compute time.

TURBOMOLE eliminates the complications entirely

Watch the full workflow (hBN monolayer + Water adsorption) in our latest TmoleX tutorial: youtu.be/6iXuo1DzqB4

TURBOMOLE Tutorial: Silicon Crystal Geometry Optimization, Band Structure and Cohesive Energy YouTube video by Phys Whiz

Most folks know TURBOMOLE for molecules, but its periodic DFT engine is ridiculously good too. With TURBOMOLE simulating materials is a breeze and you don’t need to be a command-line sorcerer to make it work.

We just dropped a new tutorial. Check it out

Hi #compchem,
Now calculate vibrational modes of a molecule using machine learning interatomic potentials (MLIPs) such as UMA (OMol), MACE OMAT-0, MatterSim, 7Net and many more on MLIP Playground (huggingface.co/spaces/Manas...)
and yes there is a dark mode

but haven't checked the performance for different charges though so can't say about that

So will DFT lmao🤣
You need to find the spin that gives the lowest energy, just like DFT. What I will agree with though is that for compounds out of the training set it may not give the correct spin for the ground state.

What I like the most about the UMA (OMol25) model is that it can take spin and charge as the input. This is a game changer as it allows simulating a large vareity of compounds with correct spin multiplicity. Seems to be quite accurate uptil now in my tests.

Recently, MetaAI released the OMol25 dataset and the UMA model — a powerful foundation model for #compchem community.

Now, you can try UMA and 16+ other MLIPs (incl. MACE) on your own systems with an app that I developed: MLIP Playground👇👇
