How To Install cloudy on Fedora 34

cloudy is Spectral synthesis code to simulate conditions in interstellar matter

Introduction

In this tutorial we learn how to install cloudy on Fedora 34.

What is cloudy

Most of the quantitative information we have about the cosmos comes from spectroscopy. In many cases the light we analyze was produced by atoms in the first generations of stars and galaxies. The spectra are produced by dilute gas where such properties as the gas kinetic temperature, chemical state, level of ionization, and level populations, are determined by a host of microphysical processes rather than by a single temperature. Analytical solutions are seldom possible and computer solutions are needed to understand their physical properties. Numerical simulations make it possible to understand complex physical environments starting from first principles. Cloudy is designed to do exactly this.

We can use yum or dnf to install cloudy on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install cloudy.

Install cloudy on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install cloudy using dnf by running the following command:

sudo dnf -y install cloudy

Install cloudy on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install cloudy using yum by running the following command:

sudo yum -y install cloudy

How To Uninstall cloudy on Fedora 34

To uninstall only the cloudy package we can use the following command:

sudo dnf remove cloudy
