Japan User Conference 2025

At the Realis 2024 Japan User Conference, Hino Motors presented a case study using FEARCE-Vulcan for thermal analysis on their engines. While the results were strong and the simulation run times orders of magnitude faster than traditional approaches, their conclusion identified several areas where usability could be improved, particularly around setup complexity and integration of CFD coolant analyses.

This presentation highlights the improvements delivered in the 2025.1 release of FEARCE-Vulcan, driven by Hino’s feedback. Key updates include a streamlined workflow, improved default settings, clearer results visualisation, and a significantly simplified user interface. Most notably, FEARCE-Vulcan now provides a method that automatically links VECTIS 3D CFD, to predict the coolant jacket thermal load, and includes that as part of the iterative FEARCE-Vulcan FE thermal solution. This new method delivers significant efficiency and accuracy improvements as it removes manual data exchange between CFD and FE models whilst guaranteeing the correct heat transfer between the two domains.

The results of a study using these improvements was presented by Jan Hynouš at the 2025 Japan User Conference on 19 September 2025.
