Welcome to Part Two of iSpec Geometry Creation and Setting Up for Solution

Welcome to part two of iSpec geometry creation and setup for solution. In part two, we will mesh the geometry we created previously. Before setting up the mesh, let's change the display preferences. We have changed the display color of the background. Now we will generate our first mesh.

To do that, we open the meshing and select "Measure HD." We will use the default values and generate the mesh. As the mesh has been generated, the number of elements and number of nodes are updated here. We can display the mesh, create a cut plane, and look at the wire mesh options.

You can see how the mesh looks like, close to the fan zones and other regions. You can change the mesh color and the location of the cut region. Now, let's open Jesitza and hit enter. You can see where the mesh is at, on this face. Instead, we would like to see the surface mesh.

Select the fans, think, look at the surface mesh, and select the solid fill option. You can see how it looks like, and the solids are filled up. Now we look at the quality of the mesh. You can see the face alignment, and we can change the minimum and maximum value.

We can see how many elements are between these regions. When you select that, you can actually look exactly where those cells are. Similarly, for skewness, you can see all the good cells. Now we will generate a new mesh, which will be a little bit coarser.

You can see as we change to coarse, the minimum element and the gap or the edge values change. These are automatic values, but you are free to change them. Generate the mesh, and you can see the number of elements has decreased.

Again, if you change this to really fine, reduce the cell sizes, and generate, it will take a lot longer. It will be a very long process to generate the mesh. Go back to our normal mesh, generate the mesh again, and add some local sizing. Use these bodies and add local sizing to them.

Select the AGP heat sink first, use per object parameter, and add each sizing parameter. Generate the mesh again, and now we have a high number of elements. Let's save the measurements so that's no call of the Państ ax project viewer.

What you will have to do is select, right-click, object parameters, and add the specific values for cell refinement. Go ahead and create a block, double-click on the block, go to geometry, select start and length.

Control the mesh over here, go to mesh, generate the mesh, and select the bridge and the block. Go to display, display mesh, and see the surface mesh. It means selected objects. Surface mesh color is this.

So now, when you see with this current setting, the gap between the two objects has been removed. The most effective way of eliminating gaps is by snapping geometry. So let's select block one, change this to start and end, make it inactive, and use the macro to automatically set mesh settings.

Now we have 170,000 cells. Display and see how the mesh looks like. That's how we create a mesh and control the meshing strategy in iSpec. Thank you.
