About BSIM

A team of skilled engineers with a problem-solving mentality

Simulation and testing experts, with one mission: help clients to solve their engineering pains and innovate.

20 years and counting

BSIM was founded back in 2010 by Marco Brunelli, building upon his expertise in the field of CAE (computer aided engineering) and more specifically in 0D/1D system engineering simulation.

Our value lies within our People

Engineering technology is our business, but we recognize that the right tools are only part of a company’s success. The other is their people: their experience, work ethic and methods.

BSIM’s value, as a partner, lies within our people: professional, invested, detail-oriented. We care and we prove it every step of the way: when we guide a customer in the selection of a new tool, train their personnel, or go the extra mile to help solve an engineering problem they have.

We’re Certified Siemens Solution Partners

The partnership with Siemens started in 2013, when BSIM was admitted to their Siemens Solution Partner program and granted exclusive distribution of simulation tool Simcenter™ Amesim™ software. The results BSIM achieved over the following years had Siemens extend the scope of our partnership to include distribution of Simcenter™ FLOEFD™ software, Simcenter™ Flomaster™  software and Simcenter Testing Solutions.

In 2019 Siemens recognized BSIM as one of their Smart Solution Experts, confirming BSIM’s skill level and expertise with Siemens products and solutions.
