Aspherix® allows for the high-fidelity simulation of industrial-scale bulk solids mixing within complex geometries like helical mixers. By leveraging advanced GPU acceleration, the software can effortlessly track the individual dynamics and multi-body contacts of over one million multi-sized particles simultaneously. This predictive digital twin enables engineers to precisely evaluate critical parameters such as blend homogeneity, segregation risks, and particle transport rates under varying operational speeds. The resulting integrated workflow gives R&D managers the exact insights needed to optimize mixer blade design, minimize cycle times, and drastically reduce the energy consumption of large-scale blending operations.
