A subset of the WP Core Benchmark CFD Set: Deliverable 1.1., in relation to the European Union's Horizon Europe research and innovation program (HORIZON-CL4-2021-DIGITAL-EMERGING-02-10) under grant agreement No. 101080085 QCFD (https://doi.org/10.3030/101080085).  The dataset covers the raw data of using a finite volume method in the framework of HELYX (engys). It is complemented with the identical set of results using a Finite Difference approach. All cases recover an unsteady heat conduction problem. In one of the experiments, the material properties change with the space. In another experiment, the grid spacing is varied linearly.
