 +\\ 
 +  * For linear elements, the Direct Solver is recommended at a lower resolution (100-200K for 32GB RAM), and the Iterative solver at a higher resolution. \\

 +  * For quadratic elements, we recommend using the Direct Solver.\\ ++

 \\ \\
   * To accurately capture small features with linear elements, set the cell size to 1/3 the thickness of that feature.\\   * To accurately capture small features with linear elements, set the cell size to 1/3 the thickness of that feature.\\

   * A decent laptop/desktop should be able to support a resolution (number of elements in the grid) in order of millions. The maximum depends on your computer's memory and whether you choose to use the direct (high performance, lots of memory) or iterative (slower performance, smaller memory footprint) solver. ++   * A decent laptop/desktop should be able to support a resolution (number of elements in the grid) in order of millions.

 +++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, allowing clearer inspection of internal features.\\
 +  * **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.\\
