CADFEM is one of the pioneers in the application of numerical simulation and digital engineering. We are one of the largest European providers of computer-aided engineering, a long-standing sales and technology partner of the leading software Ansys, part of Synopsys, Inc.. Simulation makes a lot possible today. But because software alone does not guarantee simulation success, we offer everything that matters from one source: software and IT solutions. Consulting, support, engineering. Know-how transfer. Our Ansys Rocky software enables precise predictions of particle behaviour by analysing media flows and energy absorption rates. Wherever large quantities of particles and bodies, regardless of their size, shape, material and adhesive force, are set in motion in pouring, mixing, separating, slipping or flow processes, Rocky can help to understand and specifically improve processes.

The optimization of mixing processes with the simulation software Rocky dem Traditionally, the quality assessment of mixing processes in many companies is still based on time-consuming test series, which, especially in batch processes, provide insufficient data on the time course and the overall spatial distribution of the mixing quality. Liebherr Mischtechnik reports in our Cadfem journal article (see link on the right) how the use of particle simulation with ROCKY-DEM helps to optimise process parameters - to improve energy efficiency and compound quality as well as to save costs. With ROCKY-DEM, input parameters such as particle sizes and size ratios as well as the speed and residence time of the product could be varied quickly. An evaluation of the mixing quality was now possible over the entire mixing trough and at any time. Statements about required torques and optimum speeds can also be made in this way. In addition, statements on new developments or design changes can be made by means of simulation without the need for cost-intensive…
