4.1 Create the Mesh
4.1.1 Meshing Algorithm
Most of the mesh settings depend on the chosen mesh algorithm. Current meshing strategies available on the platform are:
​
-
Standard (recommended)
​
The available meshing algorithms depend on the chosen analysis type, but also on the CAD domain file format. For example, structural simulations are limited to tetrahedral elements (standard mesher), while most CFD cases can be solved with any of the given algorithms.
4.1.2 Sizing
-
Automatic: Element sizing is controlled by automatic fineness levels that take the geometrical properties into account.
-
Manual: Element sizing is controlled by maximum and minimum edge length.
4.1.3 Number of Processors
The setting for the number of processors defines the size of the cloud computing instance that will be used to compute the mesh. The chosen setting defines the number of computing cores (CPUs) of the machine. However, an instance with more CPUs also comes with more memory, which in many cases is the limiting factor in meshing. If unsure stick to the default Automatic option.
4.1.4 Mesh Estimation
Even before the mesh is generated, the Workbench makes it possible to get an estimated range of the number of cells and nodes that will be created along with the approximate time required and the consumption of core hours. These numbers can be seen at the top and bottom of the mesh settings panel.
4.1.5 Mesh Generation
Once all the parameters have been set additional mesh refinements can be added based on individual requirements under Refinements. Click on the ‘Generate’ button to generate the mesh.
(Multiple meshes can be created for the same simulation or the same mesh can be shared across multiple simulations in the project, given that the mesh type is compatible with the chosen analysis type.)
4.1.6 Mesh Quality
Now it is also possible to check the mesh quality visually on the SimScale platform. This facility is not available for uploaded meshes though. Once the mesh is successfully created, it is indicated with the Complete state symbol . The mesh log information and quality can be viewed by clicking on the boxed options shown below:

Basic mesh information like the number of edges, faces, nodes, prisms, etc. can be checked under the Event log.
