Abstract

Additive manufacturing (AM) in construction presents challenges due to the complexity of component design. Fabrication Information Modelling (FIM) streamlines digital design and manufacturing by partially automating the process, but evaluating component functionality requires numerical simulation tools. We propose integrating the Finite Cell Method (FCM) into the FIM workflow, as it handles complex geometries with a high degree of automation. We develop an approach to represent the digital print path models as lightweight, 3D geometrical models, seamlessly integrating them into FCM analysis. Boundary conditions are specified based on the additional information from the FIM model, with relevant surfaces automatically generated and extracted. We demonstrate this workflow through a variant study on structural wall elements with internal structures, highlighting the FIM and FCM integration in design and analysis cycles. Integrating simulation capabilities into FIM provides valuable insights during early design stages, extending the digital chain from design to fabrication information to simulation-enhanced variant studies for AM products.
