This will prompt the user to select a datum plane. Select the Cell radio button in this GUI. The datum plane created earlier will aid in partitioning the model. Hold the shift button when the three points are selected. Use figure 6 as a guideline to select the three points to create a datum plane. Under the plane menu select 3 points option. From the main menu bar go to the Tools option. As the user becomes familiar with using Abaqus and meshing techniques, mesh refinement study can be carried out to study the effect of mesh size on the accuracy of the results and the computational cost. Several approaches can be used to achieve this. This partitioning will help in maintaining the size of mesh in the area of interest. The model will be partitioned in the center horizontal direction to control the meshing in the wake region. The cylinder will be located at a distance of 8 m from the front of the model. Select the extreme left edge in Y direction.

The user will be prompted to select the second edge from which to locate the hole. The cylinder will be located at a distance of 8 m from the top of the model. Select the top X direction edge of the model. The user will be prompted to select the first edge from which to locate the hole. Select XY plane for the hole.Check the direction of the hole to make sure that the hole is cut through the model in the correct direction. Select the Type of hole as "Through All". Under the cut menu, go to the Circular Hole option. The next part involves creating a circular hole that represents the cylinder. When the link to Abaqus student edition is clicked a screen similar to figure 1 appears. By following the instructions in this tutorial one should be able to make a simple model, run the simulation and visualize the result. The size of the mesh is kept to a minimum so that the simulation can be run on any machine. This tutorial will go through the steps of making the model, assigning material properties, creating a mesh, setting up the boundary conditions and visualizing the results using the student version of Abaqus 6.14 (Student edition). Laminar flow through a cylinder is a very well documented CFD problem.
