I am trying to model a piece of metal being heated and melting from solid to liquid. I want to model how the metal is melted and the molten metal flow around the unmelted solid metal. So there will be thermal and structural analysis, also fluid flow. I am wondering if virtual fluid mass (MFLUID) of SOL 129 a good choice?
Is there anywhere I can find detailed documentation and additional reading of virtual fluid mass, especially the theory behind it?
Solved! Go to Solution.
You can try to search NX Documentation for information about Mfluid. For more source, you can try to search in NX Nastran Documentation.
However, I dont think phase change (from solid to liquid) is possible in NX yet. The FSI that NX is currently have is a one way interaction, where the Flow analysis is performed first, then following with the Structure analysis where the Flow data is mapped. 2 way interactions is not possible yet.
