NX 8.5 Advanced Simulation - problem with fluid domain

NX 8.5 Advanced Simulation - problem with fluid domain

NX 8.5 Advanced Simulation - problem with fluid domain

(OP)
During Coupled Thermal-Flow Analysis I came across such a problem: I've got a heat load closed in a casing with no holes, on the top of the casing there is a radiator. My aim is to model fluid volume both inside and outside the box. Unfortunately, after modeling such volumes which aren't connected only this outer one was calculated.
Do you have any suggestions for me?

RE: NX 8.5 Advanced Simulation - problem with fluid domain

Hi MajaNX,

Not quite clear on what is your main problem, anyway are you using Fluid Domain to create the inner and outer fluid mesh? Some suggestions:
1.Maybe you can try to use NX native mesher with TETRA4 element first and check whether it works this way. Not that fluid domain is not good as it keeps improves throughout the version, I personally prefer NX native mesher because it gives move control and allow us to visualize the mesh faster.
2. Try to define 2 fluid domains, one for the inside, another for the outside.
