 +  * 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.\\

   * Low resolutions (<100,000) will generally solve problems quickly. Intact can typically support a resolution of 10 million elements (more on powerful computers), so start small, and gradually increase the resolution until consistent results are obtained. \\     * Low resolutions (<100,000) will generally solve problems quickly.

   * 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.
