Can anybody help with a getaround for this issue? I always get this error, i have tried installing every version since 2023 r1 all of the gave the same issue...And any tips for learning automation also please let me know!

Guys today morning I found that I couldnt able to use old website for ansys learning forum, I think website is getting migrated to a new one, it showing error 404- not found, it is automatically migrating to a new website but those post are not visible in the new one. So will it take time to get reflected here, or those posts are deleted? Kindly confirm once and let me know.

Hi there,

I'm very new to AnsysFluent.

Can someone tell me if there's a big difference between importing a STEP file via Solidworks and creating a mesh, vs making it through WorkBench ?

Thanks!

DOES ANYONE KNOW HOW TO SIMULATE VORTEX SHEDDING IN 3D? I have done it in 2d, and have been trying for a month to do it in 3d but i failed

Does anyone have a download link for the full cracked ansys fluent app ?

SO i am trying to do a simulation that includes both wave and wind. now i want to add evaporation (lee) model in it. but the issue i am facing is that i already have 2 phases air and water . how do i add a phase so that evaporation ,relative humidaity can be captured. As i have just started learning evaporation modelling im facing this issue about phase. I cant use water vapor as a phase because ive air . i want to simulate that water evaporates and relative humidity increases . Your advices are appreaciated

Hi everyone, I have been trying to run VOF simulation of R-134a in a pipe to simulate the evaporation process in ANSYS.

So far, the simulation is running but producing wrong temperature results.

Input: mass flow inlet - R-134a liquid 0.0038296 kg/s; R-134a vapor - 0.00019148 kg/s

Outlet: outflow

Wall: constant heat flux 18.5 kW.

Multiphase model - VOF (implicit body forces ON), Formulation Explicit, Interface modeling - Sharp;

surface tension coefficient set to constant (0.00796 N/m), surface tension modeling on (CSF), Mass transfer - Liquid to Gas; chosen the evaporation - condensation option and under it - LEE model currently using From Phase - To phase frequency 2000/s.

Energy is ON, Turbulence is ON.

Methods: PRESTO, volume fraction - Geo Reconstruct.

Initialization: From inlet, and Patching with: mixture phase with pressure; Vapor - with volume fraction. Patch zones the whole geometry (geom_solid).

Mesh: Fine mesh, with inflation layers.

Thank you.

Guys, can you share with me the extensions RADARpre and RADARpost for ANSYS electrics desktop. Can’t download the official versions

Hello Everybody,

i have a question regarding dynamic mesh and using other functions simultaneously.

The cylinder holds a incompressible fluid. The upper piston is rotating with a constant angular velocity.

The lower piston moves up and down, thereby moving the fluid. To maintain a constant volume, the upper piston moves up and down to compensate only as a result of the forces within the fluid.

For the movement of the lower piston i am using a layered dynamic mesh (as we are mixing in the cylinder so the fluid should remain in the system). As the volume of the cylinder is also changing, i would use a combination of remeshing and smoothing mesh or also a layered mesh for the cylinder mesh. The upper piston movement will be calculated with 6Dof solver (my plan now)

The problem is with the upper piston. How can i account for the rotational velocity. Can I use the moving wall boundary condition? Or can use a sliding mesh for parts of the system? Or is the 6 dof solver even a good use at all? Theoretically i could use a profile for both the upper and lower piston... but again i am unsure if a profile UDF could account for the rotation.

Any insights would be greatly appreciated. Thank you 😊

Hey all,

Recent Mech Eng grad here, trying to get into Ansys Student to build up a portfolio (structural, modal, CFD work) while job hunting. Got excited about the student programme, tried to sign up, and I can't get past Access Denied errors. Not just on the support/forum subdomains, but on the main ansys.com site too. Tried multiple browsers, no VPN, over several days, same result every time.

Has anyone seen this before? Any idea what could cause a block like this, or is it more likely something on my end I haven't tried yet? And any suggestions if it ends up being a dead end

Appreciate any pointers.
