Command Line Usage Instructions

Overview

This instruction demonstrates the use of the Fidesys command line using the example of creating a geometric model in the form of a brick with a through hole and constructing a finite element mesh on this model. The main steps for completing this task are:

• Creating a geometric model (geometry);
• Setting intervals and partitioning schemes;
• Constructing a mesh on the geometry;
• Defining the element type and boundary conditions;
• Exporting the mesh. 

Each of these steps is described in detail in the following subsections. The geometric entity under consideration (a brick with a cylindrical hole passing through its center) is shown in Fig. 1. The identification numbers (IDs) of the curves and surfaces, which are referenced in the command line commands corresponding to each step, are also presented there. The resulting mesh model is shown in Fig. 2.
