Virfac® engines and our new born superfast GPU solver

Virfac iAM offers a disruptive technology based on a new generation solver engine entirely dedicated to the modelling of additive manufacturing. Virfac iAM is connected to the powerful Barracuda solver developed by GeonX, which runs on GPU processors bringing teraflop computing to desktop. Our new solver demonstrates amazing speed-up factors compared to conventional finite element solvers. The new Virfac iAM module aims to become the true virtual manufacturing simulator side by side to the manufacturing machine.

Virfac® Results & Experimental Validations

1

Cantilever beam

For this validation of Virfac® AM, GeonX has worked with its partner Sirris. A 316L cantilever beam was printed using different stripe angles. For each configuration, Virfac® simulations were compared against the experimental measurements showing a very good agreement. The computation time on this application was about 10 minutes on a laptop for the MACRO scale model.

Airplane Bearing Bracket

For this validation of Virfac® AM, GeonX has worked with its partner Sirris. A TiAl6V airplane bearing bracket was printed using a support designed with MAGICS (Materialise). Virfac® was used to simulate the 3D printing of the complex workpiece with a support structure representative of the one suggested by MAGICS. Residual stresses and distortions were calculated before and after the removal of the supports from the part. The computation time on this application was about 5 hours in Distributed Parallel using 12 cores on a desktop computer.
