Automation of Complex Geometries
Autonomous Mobility is already reality, why not Autonomous Meshing?
In 2017 more than $1 Billion was spent on Data Cleaning world-wide. More often than not, users spend unnecessary time preparing input geometry suitable for subsequent CFD simulations. Research has revealed that meshing activities often take up more than 50% of total time including pre-processing, simulation, and postprocessing. In addition to being time consuming, only meshing experts are able to supervise complex workflow and adjust for problems accordingly. The workflow process can vary and be costly in terms of time and efficiency. Some experts start cleaning objects within CAD while others choose to reconstruct objects and full projects. Moreover, some specialists use the provided pre-processing tools of CFD simulations and most have semi-automatic pre-processing tools to remove redundant objects, heal, and combine objects before remeshing them or wrapping 3D mesh on top. ESS believes that manual work for meshing is neither up-to-date nor time and cost efficient.
The ESS Autonomous Solution
ALSIM MERGE is a toolbox full of functionalities that are all stable on complex geometries (Fig.1). It can carry out applications that are not otherwise manually possible. Each tool can be used independently or in connection with other tools. This provides the opportunity to execute complex workflows fully automatically. ALSIM MERGE’s toolbox works effortlessly, providing automation and freeing up time for further innovation. MERGE meets and exceeds expectations by defining multistage workflows, processing and repairing complex geometries automatically, is customizable, is versatile and can be exported and used my most existing software vendors as input data. For example, CAD data is taken and all objects are moved to its global coordinate system. Often the embedded files consist of lot of redundant areas, which are automatically removed and only the relevant data of each input geometry is kept. Next, duplicated geometry is removed and sheets without thickness are inflated. At this stage, all objects are clean and contain thickness. Lastly, the belt-merge provides homogenous connections between objects (Fig. 2). If needed, a re-mesh followed by 3D meshes can be applied. ESS software can provide 100% automation on the complex multibody geometries.
