In response to the needs of GeoDict users worldwide, Math2Market continuously develops and fine-tunes unique GeoDict software features to digitally design, model, simulate, and optimize filter media and filter elements, and filters. Here, we highlight five innovations of the GeoDict 2023 release:

1. Simulation of the coalescence of droplets in the FilterDict module. The goal was to increase the efficiency of droplet-separating filters (coalescer filters), and reduce the pressure drop of coalescers, through a concerted experimental and computational development of novel filter media made of bi-component fibers. Our task was to create and implement a model to describe and simulate the coalescence phenomenon in GeoDict, which is now available in GeoDict 2023.
2. Modeling of cylindrical pleated filter elements with the PleatGeo module. The workflow for filter (macro scale) modeling and simulation was improved and now provides a more user-friendly and efficient approach, including the capability to generate/model cylindrical pleated elements and cylindrical M-pleats now implemented in the PleatGeo module. In this workflow, different designs of cylindrical pleated elements, generated with PleatGeo, are exchanged into the housing while keeping the same parameters and other boundary conditions. With this feature, the effects of varying the pleat geometry and the number of pleats on flow and filtration characteristics may be investigated fast and efficiently, instead of using external CAD software.
3. Automation in multi-scale filtration simulation: Simulation of filters on meso/macro scale using the detailed results computed from simulation on micro/nano scale. The use of fine micrometric or even nanometric fibers is an emerging approach to enhance filtration efficiency. However, running simulations of filter media consisting of, for example, two-layers with a large difference in the fiber diameters, becomes challenging. The reason is mainly the different resolutions required for each layer to have a representative domain size. A multi-scale approach overcomes this issue and accelerates the simulations by drastically decreasing the total number voxels in the computational domain.
4. Improvements in simulation of electrostatic effects in the FilterDict module. The simulation of electrostatic effects in GeoDict has greatly improved by considering electrostatic decay, i.e. the change in electrostatic field as particle loading is increasing. This effect is simulated and validated with the experimental data.
5. Possibility to run GeoDict in the Cloud to accelerate simulations and reduce computational time. A significant reduction in computational time is possible by running GeoDict 2023 simulations in the Cloud. Math2Market currently offers two main solutions, easily accessible through a “Run in Cloud” button: as Remote Desktop Usage via the Math2Market Cloud, and as User-Interface for parallel job execution via the KaleidoSimÒ Cloud.
