multiphysics data for a Molten Salt Fast Reactor (MSFR) nuclear fission analysis

3D multiphysics simulation data for a Molten Salt Fast Reactor (MSFR) core, capturing the transient behavior of gaseous fission products and a helium bubbling system. Structured as a native VTK Multiblock Dataset (.vtm), the repository contains a massive volumetric unstructured grid file (two-phase_0_0.vtu) representing the internal core fluid dynamics, alongside multiple polydata surface files (two-phase_1_0.vtp through two-phase_7_0.vtp) that map specific boundary patches and inlet walls. The data arrays track localized, synchronized physical attributes across tens of thousands of spatial nodes—specifically documenting helium gas void fractions (alpha.air), fluid velocity vectors ($U$), temperature gradients ($T$), and xenon concentrations—providing an authentic, highly complex structural topology for fluid and neutronics visualization pipelines. base reasearch pdf included.
