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”
