Cutting-Edge Free Tools To Unlock the Power of Computational Chemistry

Computational chemistry is a rapidly developing field that uses advanced computer simulations to study the properties and behavior of chemical systems. In recent years, many cutting-edge open source tools have been developed that allow researchers and scientists to perform complex calculations and simulations on their own computers. These tools offer a wide range of capabilities, from basic quantum mechanics calculations to sophisticated molecular dynamics simulations, and can be used to tackle a wide variety of problems in chemistry, materials science, and other related fields. In this blog post, I will introduce you to some of the most promising and powerful tools in computational chemistry that are available today.

Most of these tools can be run on a wide range of computers, from laptops to HPC clusters, and different operative systems including Linux, Windows, and Mac. Additionally, all of them are completely free to use, making them accessible both to researchers and scientists or the general public interested in running their own simulations. However, it's important to note that some of these tools require a license for commercial use, so if you plan on using them for business purposes, make sure to check the licensing terms carefully.  These tools are really powerful and versatile, but also have an entry barrier, not very difficult to overcome though with a bit of effort, so whether you're a seasoned computational chemist or just starting out in the field, you're sure to find something here that will pique your interest.

This list is far from being complete, but I believe it covers a good amount of tools that can produce the highest quality simulations to date. I will keep updating the list, so you can bookmark this link and come visit every now and then. Note that most of the descriptions of each code here are taken from their respective websites. The classification is not always strict, as many codes can do many things so would fit in different categories. With all that in mind, let's take a look at some of the most exciting and innovative tools in computational chemistry that are available today.

  • Mamba is a reimplementation of the conda package manager in C++. Conda sometimes struggles and is really slow at solving the environment. Mamba is extremely fast and fixes this an some other issues.

Software Installation

To install the codes listed here, you have two options: either contact the administrator of your HPC or do it yourself. The most efficient method (performance wise) always will be to generate the binary in your working machine by compiling the code and linking it the the also compiled and optimized libraries in your specific machine. This is not always an easy task, but is what generates the most efficient code. If you are going to run complex and expensive calculations, this will be the way to go. Your administrator can do it, or you can do it yourself if you know how (usually it is painful).

If you want to run small or medium size simulations, were performance is not a big issue, or you want to try the tools and learn how to use them, the best method I've found so far is using Conda, and create a virtual environment. Conda not only manages Python modules, but it also can install many different precompiled packages. It deals with the dependencies and environment variables, and it can even generate binaries that run the code in parallel! If the codes you want are in the Anaconda repository (and most of them are), the steps you may want to follow are:

  1. Install miniconda for your OS. Does not require admin permissions.
  2. Create an environment
    conda create -n environmentName
  3. Activate your brand new environment
    conda activate environmentName
  4. install in your environment the packages you want
    (environmentName) $ conda install -c conda-forge package1 package2

    alternatively, you can use mamba instead of conda to install the packages

    (environmentName) $ mamba install -c conda-forge package1 package2

Well, if you've reached this far, congratulations! I hope you found something useful in this list and you can use for your own research. If you think i really missed some important code or you just want to share something, just leave a comment, send me a message or joint the community in the Quanticorum server.

I want to thank Dr. Fernando Izquierdo Ruiz and Dr. Philipp Marquetand for their kind contribution to this list.
