MATLAB CSG Tool and Point Boundary Conditions 4

Step 4: Assemble and Solve Global System

Select Static under the Solver menu. This assembles and solves the global matrix. Verify that under Current Settings, the software reports Displ. done. Let's take a look at the nodal displacement values to check that they look plausible.

Nodal Displacements

Under Plotting, select Displacement. The nodal displacements are shown below.

Are the displacement boundary conditions at A and B satisfied? The displacement is largest in the middle section of the beam. Is this what you'd expect?

Deformed Mesh

Let's take a peek at how the elements have deformed under the applied vertical loads. Under Plotting, select Deformed mesh. Enter 1000 for the magnification factor and click OK.
