![]() Isovolumes serves as a filter to isolate elements, whose volume ratio falls under a defined range. The best way to locate the bad quality elements is to isolate them and to do this we can use Isovolumes. However, the current view can only show the surface elements. To visualize the volume ratio, do the following:įigure 4: Mesh volume ratio in mesh quality viewer.Įverything in blue shows that the volume ratio is small in the overall domain. In this example, we are only going to focus on reducing the maximum value for our volume ratio. You will find this feature below the Meshing Log. The Mesh quality is a SimScale feature, which visualizes the element quality. Now, we have learned how to identify a bad quality mesh, but what is the cause and where are these bad quality elements located? Let’s find out. The picture above shows that our mesh has bad quality because the maximum volume ratio is 93. Below are values that can be used as a best practice reference on when to check and improve your mesh quality:įigure 3: Example of bad mesh metrics. ![]() It is worth keeping in mind that we need to monitor these values because it will affect the result of the simulation. These results will be mentioned as mesh metrics and these metrics will differ depending on the mesh type. In the meshing log, you will find the statistical results of your generated mesh. You will find the Meshing Log under the Mesh settings in the simulation tree. Meshing Logįirst, generate the mesh and once the mesh has been generated, you can see the mesh quality in the Meshing Log. The picture above is the initial mesh that will be used as an example. ![]() The standard mesh can have both tetrahedral ad hexahedral elements. ![]() Using manual mesh refinement to improve mesh quality.įigure 2 : Initial standard mesh on a pump.Using the Mesh Quality feature to locate bad elements.Checking the Meshing Log to have a quantitative idea about the overall mesh quality.Please visit this tutorial to learn how to use the standard mesher within SimScale. In this article, we will use the Standard mesher as an example. Figure 1: Mesh elements with volume ratio > 4 highlighted ApproachĪ high-quality mesh is one of the most critical factors that must be considered to ensure simulation accuracy, and this is why it is very important to check and improve your mesh quality. ![]()
