In 1999, the XC90 was modelled with 300 000 finite elements.

In 2014, the XC90 gen II was modelled with 10 000 000 elements.

Detailed deformations including fractures, acceleration pulses, dummy behaviour etc. predicted well enough to lead product development process including sensor calibration.

CAD driven vs CAE–CAD integrated development

Collaboration around design space and performance analysis, many concepts and performance evaluation

Starts with earlier project and experiences, few concepts studied, time consuming iteration
