Case Study: Dr. Reddy's Laboratories achieves accurate, lower-risk scale-up (50% uncertainty reduction) with ANSYS simulation consulting

Dr. Reddy’s Laboratories - Customer Case Study

Dr. Reddy’s Laboratories engaged ANSYS to tackle a costly, time-sensitive scale-up challenge: moving complex mixing processes from lab scale to plant scale while coping with limited and expensive raw materials. Using ANSYS Consulting and simulation products (ANSYS CFD, SpaceClaim, Mesh and Fluent), they sought faster, physics-based process understanding to define accurate scale-up conditions for mixing tanks and reduce risk.

ANSYS consultants performed steady-state and transient simulations to study velocity distributions, micro/meso/macro mixing times, species concentrations, dead‑zone formation and rpm-related risks, informing equipment sizing and test strategies. The ANSYS work delivered measurable impact—cutting expensive test material use, enabling engineering-driven decisions and reducing uncertainty in identifying the correct process window by 50%, thereby lowering overall scale-up risk.
