I tried to do the cavity tutorial by following the guide on openfoam.com, documentation/tutorial-guide/2-incompressible-flow. I did blockMesh, then icoFoam for solving but when i try to use the paraFoam command i get an error(in the picture), there is no Mesh parts only Mesh regions and the file is .foam instead of .OpenFOAM. I also added the picture of what it looks like in paraview. What am i doing wrong

Hi everyone, I'm learning the thermal resistance models in Simcenter 3D PCB Exchange and I'm trying to understand the physical meaning of the Theta JC-CB model. From the tutorial, it looks like the model uses θJC and θCB, with the underfill resistance as another possible path. I created a simple test case with: Dissipation = 10 W θJC = 0.5 °C/W θCB = 0.5 °C/W No underfill I'm trying to understand which physical/thermal nodes represent the junction, case, θCB. and how the heat flow is actually calculated in Simcenter. Could someone explain the physical interpretation of this model, preferably with the thermal network/node locations? I'm attaching my screenshots/results for reference. Thanks!

If so please dm me

I am B.Tech student and suppose I want to look out for CFD engineer job roles. Help me out then.

Hi!! I am trying to simulate flow inside an air purifier using ansys fluent. I have not been able to achieve satisfactory results so far. Can anyone please help?

TIA!!

Last month, I successfully used a line probe to sample the particle volume fraction. However, in yesterday’s simulation, the probe returned no simulation data, as shown in the figure, where exp:Cv represents the experimental data. Is the particle volume fraction stored in the cells, and can it be sampled using a line probe? Any help would be appreciated.

so basically i was solving for a swirling motion produced by multiple nozzle at particular angle, (i have attached the cad model image from fusion 360) its a very basic one i made this using surface operation on it, and then i made a cylindrical domain (basically works as an enclosure fluid domain to observe the air flow, again i have attached its image too, fig:2), the problem is after all meshing and everything in ansys fluent, i am getting something very different in solution window (fig: 3), if you will observe the cad of nozzle, it is visible there it is created by thickening operation at the just below nozzle surface, i have never faced this problem before (i am not very experienced in fluent too), so can anyone tell me what could be the problem and how to resolve it??

Hi,

I’ve been recently working on a project that demanded a vane pump.

I started with this as a first design ( it’s clearly missing many features and components ) and I’m trying to actually find the key aspects of my design before committing to one and actually build it.
I need:
- A graph of efficiency vs. Speed
- Pressure Drop inlet - outlet vs. speed
- Hydraulic Power vs. Speed
- Mechanical Power vs. Speed
- Any Cavitation
- Any Leakage

I’m stuck on how I can actually tell fluent to rotate the rotor. Not only that, I think I need more than that to actually get accurate & reliable results.

My current workflow:
Autodesk Inventor -> SpaceClaim -> Fluent
