Tutorial-v.1.0.0

In this tutorial, we explain the use of SALMON from the very beginning, taking a few examples that cover applications of SALMON in several directions. We assume that you are in the computational environment of UNIX/Linux OS. First you need to download and install SALMON in your computational environment. You may find detailed instruction in download-v.1.0.0 and install and Run-v.1.0.0.

As described in Install and Run-v.1.0.0, you are required to prepare at least input file and pseudopotential files to run SALMON. In the following, we present input files for several example calculations. We provide a brief explanation of the namelists that appear in the input files. Pseudopotential files of elements that appear in the example are also attached. We also present main output files and explain what they include.

You can run SALMON at your own environment just getting files from this page. You may also be able to modify the input file reading the explanation of the namelists.

We present 6 samples. First 3 samples are for an isolated molecule, acetylene C2H2. In SALMON, we usually calculate the ground state DFT solution first. This is shown in Sample-1.
