Generally, quadratic elements converge to a good answer quicker and with few elements, but it depends on the simulation scenario.\\ | * Regardless of the scenario, either will work.

| + | ++3.1 How can I turn on/off display mesh visualization? | ||
| + | \\ | ||
| + | * Intact plots results using a display mesh. The result values are sampled on the mesh vertices and then linearly interpolated within the mesh facets based on the facet nodes.\\ | ||
| + | * To turn on or off this display mesh, see the steps in the video below\\ | ||
| + | * Seeing the display mesh can be useful to ensure if there a visualization artifact due to the display mesh. \\ | ||

| + | |||
| + | ++3.2 How to create sections in the visualization using Rhino Clipping Plane?| \\ | ||
| + | \\ | ||
| + | * Use Rhino’s `ClippingPlane` command to insert a plane that intersects the geometry you want to section.\\ | ||
| + | * On the Grasshopper canvas, insert a `GUID` parameter block.\\ | ||
| + | * Right-click the `GUID` block and choose “Set one GUID.” Then select the Clipping Plane object in Rhino.\\ | ||
| + | * Once the GUID is linked to the Clipping Plane, the visualization should automatically update.\\ | ||
| + | * The simulation geometry will be sectioned and filled accordingly, | ||
| + | * **Note:** Moving the Clipping Plane in Rhino will *not* update the sectioned geometry in Grasshopper. This is because the `GUID` block only captures the object’s identity—not its dynamic position or orientation.\\ | ||
