Reading this manual
If you are new to Octopus it is recommended that you read this manual sequentially. To read this manual you need some basic knowledge of Density Functional Theory (DFT) and Time Dependent Density Functional Theory (TDDFT), also a bit of numerical methods may be useful.
The way to tell what to do Octopus is through input variables, each one of this variable has its proper documentation describing what it does and what are the possible values that it can take. All this documentation of the variables is contained in the Reference Manual Appendix. That information is complementary to this manual, here we will only give a brief description of the function of each variable and we will leave the details for the Reference Manual. If you are reading an electronic version of this manual, all references to input variables will be marked as hyperlinks, opening that link will take you a page with the reference documentation for that variable.
There are some styles used in this documents: "proper names" (like Fortran), "files and directories" (like inp or /tmp/), "commands" (like ls) and "
input file text" (like
