redAnTS TUTORIAL: CSG Tool and Point Boundary Conditions
This redAnTS tutorial solves a beam bending problem and in the process shows you how to
 Generate a mesh using the CSG Mesh Tool.
 Set boundary conditions at a point.
It is assumed that you are familiar with the introductory redAnTS tutorial.
Problem Specification
Consider the beam in the figure below. There are two point forces acting on the beam in the negative y direction as shown. Note the dimensions of the beam. The Young's modulus of the material is 73 GPa and the Poisson ratio is 0.3. We'll assume that plane stress conditions apply.
We'll put redAnTS to work on solving this problem using FEA. We'll plot displacements and stresses for the beam and make comparisons with theory.
Solution Steps
We can use the same steps as in the introductory tutorial to obtain the FEA solution:
 Step 1: Startup and preliminary setup
 Step 2: Generate finiteelement model
 Step 3: Specify inputs
 Step 4: Assemble and solve global system
 Step 5: Postprocess the solution
Let's dive into step 1 without further ado.
