There is the inconsistency in units for non-Newtonian viscosity calculations in the Herschel-Bulkley model. The inconsistency arises because the model expresses shear stress (tau) in units of N/m^2 (Pascals), while the shear rate (gamma_dot) is in units of s^-1 (reciprocal seconds).

2D Homogeneous Isotropic Turbulence (HIT) Simulation in Ansys Fluent: A Beginner's Guide
Setting up a simulation for 2D homogeneous isotropic turbulence (HIT) in Ansys Fluent requires defining a specific flow condition. While Fluent itself may not have a pre-configured template for HIT, you can achieve this by following these steps:
Ansys Electronics Desktop Mesh Quality Error: Solution and Troubleshooting
The error message you're encountering in Ansys Electronics Desktop
The quality of some mesh elements is not acceptable for solution. Please check the geometry for issues in the following location..
indicates that the mesh quality in a specific location (X=0.00536424, Y=-0.0146285, Z=-0.0061444) is below the acceptable threshold for accurate simulation results. Here are some steps you can take to address this issue:
OpenFOAM Error: Carrier Phase curlUc Interpolation Object Not Set (SaffmanMeiLiftForce)
The error message "Carrier phase curlUc interpolation object not set" in OpenFOAM indicates that a required interpolation object for the Saffman Mei lift force calculation is missing. Here's how to address this:
Fitting Rheology Data to PTT or Maxwell Models for OpenFOAM Simulations
Converting rheology data to model parameters is definitely possible! Here's a general approach for fitting your complex rheology data (G*, G', and G'') to the PTT or Maxwell models using OpenFOAM:
Exporting Airfoil from DesignFOIL to AirfoilTools for Impeller Design
DesignFOIL allows exporting airfoil coordinates in various formats, including DAT files. However, AirfoilTools specifically requires a DAT file format with a header containing specific information about the airfoil.
