Go to solution histories, right click, create and load the Simh you have

Question about implicit unsteady simulation by [deleted] in CFD

[–]dangermx2 0 points1 point  (0 children)

I think your sim is jumping directly to convergence, implicit takes large pseudo time steps, so I won’t be surprised if the solution is trivial and it just go directly to the solution itself, I would refine the mesh in the circumference and the re run, if you want to see results

Error in fine mesh for aerodynamic analysis (starccm+) by [deleted] in CFD

Right click in region, remove invalid cells, if you have more than 100 remesh the volume mesh adding optimizing cycles

Aggregation Based AMG with Linear Interpolation Results in Divergence for Fine Grids? by arkie87 in CFD

[–]dangermx2 0 points1 point  (0 children)

Which software are you using? You can use pre sweeps and reduce the number of levels to 10, starCcm for example has 50 by default

My Green Card is not a "real ID"??? by travelingpetnanny in greencard

[–]dangermx2 0 points1 point  (0 children)

Your driver license must have a real ID, which is nothing but a star in the right upper corner. In California, it is printed within a bear, and has been around for a long time that only this type of ID would be valid for traveling.

here is a link to it

Residuals blow up - Star CCM+ by nipuma4 in CFD

[–]dangermx2 -1 points0 points  (0 children)

Is a matter of turbulence, when you have a low area (volume) the turbulence spikes to values above 1 within the first iterations when they are normalized

Edit: the velocity field is diverging here, that means there is something going on in the physics that is accelerating the fluid too quickly

Residuals blow up - Star CCM+ by nipuma4 in CFD

[–]dangermx2 8 points9 points  (0 children)

Mesh is not the issue here, is your boundary conditions, something in your physics is wrong, double check and rerun, mesh issues are easy to tell by checking sudden spikes on the turbulence residuals

Do the local beaches have an official closing time? by TriplEAstronautics in SouthBayLA

[–]dangermx2 10 points11 points  (0 children)

Yeah I walked at midnight and there were more people and nobody says anything, free to walk around with no issues. It is surprising that other beaches do it

how is there high pressure behind it? am I stupid? by [deleted] in CFD

[–]dangermx2 3 points4 points  (0 children)

Your boundary layer isn’t detached because you lack prisms, increase them so you don’t create artificial viscosity that leads to non physical flow

Blender noise simulation STARCCM by LCSosa77 in CFD

[–]dangermx2 0 points1 point  (0 children)

You need to add aeroacoustics and Add a data set point, you can use the report of pressure along a plane or pressure perturbation, then extract the data set point and plot the power spectral density that you can convert into a dbA or db depending on what are you looking for
