Case Study


DENSO is a leading Japanese automotive and Fortune 500 company.
Hiroshi Ogawa, at DENSO’s Heat Exchanger R&D Division, implemented a custom FreeFEM model on TANATLOC with the help of Professor Atsushi Suzuki from Osaka University.
DENSO’s Solder Filling model was added to TANATLOC, and the calculations are deployed seamlessly on the cloud or on on-premise server via the ANCL Sharetask plug-in.

Tanatloc is an FEA software based on FreeFEM, an extremely powerful and versatile open-source PDE solver. It runs locally using an electron build.
