When you move the mouse pointer over the SCA regions on the right side of the drawing, the material assigned to each region is displayed in the status bar. You will notice that the material assigned to the region in the middle of the tube is AlSi, which stands for the sample. If you want to enlarge the sample, you need to edit this region.

For editing the geometry you have to switch to Geometry Mode:

Select Mode > Geometry.

Only the right side of the furnace is now displayed in the Main Window, and you can see how the SCA is composed of points and lines:

Zoom in the area of interest by selecting the sample area with the left mouse button.

Now you select the points and lines you want to move. You can cancel the selection of points and lines in the same way you select them, or click Edit > Unselect all to cancel the selection of all selected elements.

Select the bottom line of the sample region and the two points at the ends of the line by clicking on the points with the right mouse button. Your drawing should approximately look like this:

Now you are prepared to change the size of the sample.
