DIMAXER

Revolutionary High-Resolution Industrial Simulation Software

DIMAXER is an industrial-grade CFD simulation software independently developed by Rankyee Technology. Its core STE-KEP-FR algorithm has been iterated and upgraded for 18 years and evolved to the 5th generation. For unsteady simulation of large-scale, multi-scale and complex industrial scenarios, it achieves a breakthrough cost-performance advantage: <b>supercomputing-level performance at workstation costs</b>, pushing CFD simulation to the cutting edge of high-fidelity, low-modeling / model-free simulation. The software supports high-order meshing for complex component geometries, fully compatible with structured and unstructured meshes. Overset mesh technology enables precise representation of arbitrarily complex geometries and drastically lowers preprocessing barriers. It also features a user-friendly GUI, covering the full numerical workflow of meshing, solving and post-processing for one-stop simulation.
