To help with refining your CFD model for stirred tank mixing time validation. Here are some potential reasons for the discrepancy between your CFD results and the laboratory measurements, along with suggestions for improvement:
Possible Reasons for Discrepancy:
There are a couple of reasons why non-dimensionalizing your hypersonic intake geometry might affect the captured flow pattern with flow separation in your streamtrace:
Absolutely, I can help you with running CFX coupled transient structural analysis on Linux without a GPU.

Entering a small thickness like 1.5 mm into a large domain in ANSYS Fluent can be challenging due to meshing limitations and potential contact issues. Here are some approaches to consider:
Unfortunately, ANSYS Fluent doesn't offer a direct way to modify the number format for DPM (Discrete Phase Model) sample output. The output format is typically fixed in scientific notation (e.g., 1.1e+00).
Here are some alternative approaches you can consider:
Here's a breakdown to solve beam vibration problem of the general process after obtaining the equations from your free body diagram:
The DTRM model likely focuses on illumination parameters relevant for visible light rather than the entire solar radiation spectrum. Here's how to provide a more comprehensive input model for solar radiation in Ansys Fluent:
It sounds like you're encountering an unphysical increase in velocity for your bubble as it reaches the surface in your VOF-DPM coupled simulation. Here are some potential causes and solutions to consider:👽👿
Several factors can influence the presence or absence of a gas layer at the bottom of buried tubes in a Eulerian two-fluid fluidized bed simulation:
In multicomponent flow simulations without reactions, the exact value of the molar mass for each component doesn't significantly affect the mass fraction results in ANSYS CFX. Here's why:
Here's how to address your questions about plotting pressure change and determining pressure drop in ANSYS Fluent:
Plotting Pressure Change:
* Surface Reports: Utilize Surface Reports in ANSYS Fluent to obtain average pressure values at the inlet and outlet faces.
Iso-surface movement during SLM simulation in ANSYS can be caused by several factors. Here are some potential causes and solutions to consider:
👽
* Inaccurate Melt Pool Dynamics: The melting behavior of the powder might be misrepresented in your simulation. Calibrate your material properties, laser power settings, and melt pool viscosity to better reflect reality.
* Meshing Issues: A coarse mesh might not capture the melt pool dynamics accurately. Refine your mesh, particularly around the laser-powder interaction zone, to improve precision.
There are two possible reasons why you might not be able to see the vorticity contours in ANSYS CFD-Post:

The unexpected velocity increase in your partially filled stirred vessel simulation could stem from a few factors:
Hey everyone,
I have a weird problem with my simulation of a stirred vessel partially filled with water. Above the air-water interface, the velocity of water (UWater) gradually increases over time and I can't figure out why. I think this increase over time causes my simulation to fail after simulating a few seconds
I mostly used the case from this link as a reference: https://www.cemf.ir/simulating-two-p...sing-openfoam/
I can't figure out what the problem is for the increase. Does anyone know what could be the cause for this or had similar issues in the past?
There are two main approaches to porting the initial field from a StarCCM+ simulation to an OpenFOAM case:
* Using ccmToFoam: While ccmToFoam can convert the mesh, it may not directly translate the initial field data. You'll need to manipulate the converted data to match OpenFOAM's format.
In OpenFOAM, you can simulate rough wall effects in your pipe flow simulations using the roughWall function object. This function alters the logarithmic law of the wall to account for the increased drag caused by the roughness.
To access the raw GeoJSON string within a nested part of your server response without decoding the entire structure, you can use the decodeIfPresent(_:forKey:) method of the Decoder object. Here's how you can modify your code:
I am trying to install the OpenFOAM 11 version of thew software on my Windows server 22 OS through WSL. I followed the documentation based on the 4 steps mentioned here.

While sourcing the bashrc file through my $HOME directory, I am getting the following errors as shown in the image attached. Do I need to make any changes in the User editable portion of the bashrc script?
