The Ifc-To-Code_Aster project (https://github.com/Jesusbill/ifc2ca) is progressing and we have released a web structural BIM viewer to facilitate the conversion of IFC structural models to JSON for configuring and running analyses with Code_Aster.
You can see the viewer here, along with the examples in the repo: https://www.aethereng.com/#/ifc_structural_viewer
I am in the process of creating more complex examples to support many aspects still missing but if you have any model you care to share it would be very welcomed, thank you in advance
