Automated meshing procedures are crucial in CFD simulations and generative thermal design. In this article, we'll explore why using a robust and automated meshing procedure in ColdStream is important and the benefits it can bring to your simulation projects.

CFD and thermal simulations require a mesh or grid to define the analyzed model's geometry. The mesh is used to solve equations describing fluids' behavior and heat transfer. The quality and accuracy of the mesh have a direct impact on the accuracy and reliability of the simulation results.

An automated meshing procedure helps ensure that the mesh is of high quality and accurately represents the geometry of the analyzed model. It eliminates the need for manual meshing, which can be time-consuming, error-prone and require specialized expertise. Such a procedure can also adapt to changing geometry, so as the design process evolves, the mesh can be updated to match it.

One of the biggest benefits of an automated meshing procedure is increased productivity and efficiency. Manual meshing can take hours or even days to complete, especially for complex geometries, because of the difficulty of finding suitable parameters for a given geometry. With a robust automated procedure, the mesh can typically be generated in a matter of minutes, freeing up time and resources for other tasks.

This also means that multiple scenarios or designs can be simulated in a shorter amount of time, leading to faster design iterations and quicker product development. Consistency will be guaranteed across these different scenarios of the same problem, which can be difficult to ensure when meshing is done manually.

Additionally, automated procedures can enforce quality standards, such as element size and shape, to ensure that the mesh meets the requirements for accurate simulation. High-quality mesh elements can also provide improved computational efficiency, reducing simulation time and enabling the analysis of more complex models.

Finally, generating meshes in an automated way will help to reduce costs. Manual meshing can be expensive, requiring specialized expertise and time-consuming manual labor. An automated procedure eliminates the need for manual meshing, reducing labor costs and freeing up resources for other tasks.

An automated meshing procedure is a key component of efficient and accurate CFD and thermal simulations. It can improve productivity, consistency, accuracy, and quality while reducing costs. By incorporating such a procedure into our simulation workflow, ColdStream can ensure that your simulations are fast, accurate and reliable and that your product development cycle is as short and efficient as possible.
