3. Mesh

For the mesh we will generate a mapped face mesh with 200 elements. The horizontal edges will have 10 divisions and the vertical edges will have 20 divisions.

Mapped Face Meshing

For this simulation we will use a mapped face mesh. A mapped face mesh is that a mesh that can be mapped to a rectangular domain. The domain for this simulation is already rectangular, thus mapped faced meshing will yield a rectangular grid mesh. In order to implement the mapped face meshing, first (Click) Mesh, SimCafe > 2D Steady Conduction - Mesh > MeshButton.png . Next, (Click) Mesh Control > Mapped Face Meshing, as shown below.

Then, click on the rectangle and it should highlight green. If it does not highlight green, click on the face selection filter button, SimCafe > 2D Steady Conduction - Mesh > faceselect.png

,then click on the rectangle. Once the rectangle has been selected (Click) Apply in the "Details of Mapped Face Meshing" table as shown below.

Now, (Click) Update, SimCafe > 2D Steady Conduction - Mesh > UpdateButton.png

, in order to generate the mesh. You should obtain the following mesh.

Edge Sizing

At this point the number of divisions along the sides of the rectangle will be specified. We will us 20 divisions along the vertical sides and 10 divisions along the horizontal sides. We will work with the horizontal side first. In order to implement the edge sizing, first (Click) Mesh, SimCafe > 2D Steady Conduction - Mesh > MeshButton.png . Next, (Click) Mesh Control > Sizing, as shown below.

Next, click on the edge selection filter, SimCafe > 2D Steady Conduction - Mesh > edgeslectfilter.png

. Then click on the bottom edge of the rectangle and (Click) Apply in the "Details of Sizing" table as shown below.

Next, set Type to Number of Divisions and set Number of Divisions to 10, as shown below.

This completes the sizing for the horizontal edge. Now, create a new edge sizing, apply it to the right vertical edge and set the Number of Divisions to 20. After, you have properly implemented the two edge sizing commands, (Click) Update, SimCafe > 2D Steady Conduction - Mesh > UpdateButton.png

, in order to generate the new mesh. You should then obtain the following mesh.

This completes the meshing process for this simulation.
