The Bosch reference
“Siemens PLM Software has proved to be an excellent
partner, one that listens closely to Bosch’s requirements and
takes them into account in the LMS Imagine.Lab roadmap.”
“More than 300 Bosch engineers use LMS Amesim in
different locations globally to create specific components”
“… open simulation tools are critical to avoiding what
otherwise is likely to become a time-consuming and error-
prone process.”
“Another very important advantage of LMS Amesim is its
strong focus on numerical performance and robustness”
