Abstract
This paper expands the possibilities of the Ansys Fluent program in way of using a text user interface instead of a graphical one.The main goal of this work is the optimization of the analysis preparation process and implementation at every stage.It can be achieved by using text commands stored in the input file (log) which is readable by Fluent.Preliminary CFD analysis results show that such a method is useful for many cases.Especially it can accelerate daily routines if there are a lot of boundary conditions, input data, materials, energy sources, and other things to operate in the solver setting process.Also using the command log makes it easier to work on complex projects in groups.
