What Fluidimensions does

FluiDimensions is a privately held engineering simulation and consulting firm founded in June 2016 by Dr. Vivek Vitankar and headquartered in Pune, Maharashtra, India. The company provides computational fluid dynamics (CFD) modeling, multiphysics analysis, equipment design, process optimization, and debottlenecking services to industrial clients across ten verticals including chemicals, pharmaceuticals, cement, metals, power, agrochemicals, paints, food and beverage, automobile, and oil and gas. Its work covers multiphase reactors (gas-liquid, liquid-solid, gas-liquid-solid), stirred tank design, cyclone separators, kilns and calciners, combustion modeling, and electrostatic precipitators, applied to problems such as mixing inefficiency, heat transfer optimization, scale-up, emission reduction, and energy efficiency.

The firm executes projects using a stack of industry-standard tools (ANSYS Fluent, STAR-CCM+, ASPEN Plus, DWSIM, MATLAB) complemented by custom code in C/C++, FORTRAN, Python, R, and Excel-VBA, and offers CFD process automation that wraps the full geometry-to-post-processing workflow for non-expert users. A newly developed AI for Chemical Process Industry service integrates machine learning and neural networks with first-principles modeling for predictive analytics, fault detection, and process optimization using historical process data. The firm also resells or implements Siemens' Simcenter CULGI for molecular and materials modeling.

FluiDimensions operates a sales-led, relationship-driven go-to-market targeting enterprise manufacturing clients, with project-based, quote-priced professional services engagements initiated through the website, direct email, or its 'CFD Cafe' exploratory concept. It supplements client work with online CFD training programs and academic collaborations with institutions including ICT Mumbai, NIT Meghalaya, IITRAM Ahmedabad, and Walchand College of Engineering. The firm is privately held by the founder, reports a headcount of 1-10, and has not disclosed external funding.
