ThermalParallel

The data needed to execute the tutorials below can be loaded here: exampleThermalParallel.zip

This use case aims to validate the methodology POD + ECM for nonlinear transient thermal computations in parallel with distributed memory, see Section Publications, article 2.

No optional prerequisite: notice that even if the HFM snapshots are computed here using Z-set, the ROM do not require any Z-set license to be run.

Features: parallel with distributed memory

The physical setting, workflow and reduction strategy are the same as in the tutorial ThermalSequential, hence we only point out the differences here: the parallel setting and the dimensionlality of the test (3D), see Fig. 19. The problem still features a nonlinear material, convection heat flux and radiation boundary conditions.

Results

In Fig. 20, the quality of the reduced model is illustrated by comparing it to the high-fidelity reference. The comparison is done on the temperature field.
