Meshing with TMESH/SnappyHexMesh

Hi everyone,

I am thinking about using the TMESH module to mesh my geometries via SnappyHexMesh and I was wondering if you have any recommendations (regarding the values and significations of the different parameters for example)? Any advice or material would be really helpful.

Thank you very much and have a nice day,
Alex

condensation and humidity simulation

Hello all,


As a newbie to OPENFOAM software, I'm actually trying to redo the simulation from the article (Simulation of Moisture Ingression in Microelectronics Package to Correlate Accelerated Tests and Field Conditions Reliability). The authors used Comsol software for this simulation. I was curious as to whether this was possible with OPENFOAM.


Thank you.

ACOUSTIC-BENCHMARK-PROPELLER-DJI9450 CAD MODEL

Hello sir

i had gone through your webinars and various papers. recently i had read your published information regarding <TCAE-CFDSUPPORT-ACOUSTIC-BENCHMARK-PROPELLER-DJI9450> . I want to try simulation on same propeller can you please provide me cad model for dji9450 propeller that you had used in Ur simulation.

 THANK YOU

Tool flow from Solidworks to TCAE

What is your recommended tool flow from Solidworks to TCAE that preserves surface names (inlet, outlet, walls etc) ?

 

My understanding is that unfortunately Solidworks does not preserve surface names when exporting the model as an STL file and exporting surfaces as separate STL files will produce non-conformal vertices.

 

Does one need to go through a third-party mesher ? I believe the Solidworks .step export preserves surface names. Is the recommended tool flow to go through a package such as Salome to create separate (but conformal) stl surface meshes ?

NACA 4412 study case

Hello 
I have some questions about the NACA 4412 case file provided in cfd support study cases:
1- how to set the simulation for other meshing (structured ones) that I did using block mesh please.
2- Trying to run the case without making any change gives this error. I tried to solve it many times without success. any suggestion on how to solve it especially for the solver related ones (rhomin....)
here the error message:

rhoSimpleFoam convergence

Have you got any advice or sample files (fvSolution, fvSchemes) for getting rhoSimpleFoam to converge please?


I'm running an aircraft case at Mach 2.0, using rhoSimpleFoam, with freestream BC in the far-field.

The whole solution becomes very oscillatory, even though initial convergence looks ok. I am using relaxation factors and limiters that have worked for me before.  I have used rhoSimpleFoam many times before for supersonic applications, but this time I'm having difficulty.
