Good afternoon everyone, could someone help me? I am working with porous media and I want to set a random porosity in my domain. I tried a DEFINE_PROFILE, but it calculates random values ​​for my porosity at each iteration, but I only want it to calculate the profile once and use it for the rest of the calculations. I tried creating a DEFINE_INIT, and I was able to initialize random values ​​and associate them with a UDS variable, but I can't associate these values ​​from the profile generated in the cell zone conditions. Does anyone have any ideas?

Hello everyone, I recently graduated with a degree in Fluid Mechanics and have prior experience with simulation projects, primarily using COMSOL and OpenFOAM. However, I’m new to STAR-CCM+ and would like to perform CFD simulations for mixers. From my initial research, it seems that the MRF (Multiple Reference Frame) method is widely used for such simulations. That said, I’ve come across limited tutorials specific to STAR-CCM+, and I’m hoping to get some advice from experienced users of this software. Specifically, I’d appreciate guidance on: 1. Mastering STAR-CCM+: Tips, resources, or learning strategies that can accelerate my understanding of the software. 2. Simulating Mixers: Best practices, common pitfalls to avoid, or any specific workflows/tutorials for modeling mixers. Any recommendations, resources, or insights you can share would be greatly appreciated. Thank you!

I've been trying to learn OpenFOAM and SplashFOAM looks like a blessing so far. As I am trying to mesh following the SplashFOAM webinar on YouTube, I get the error saying openfoam2306 is unavailable. I wanted to see if I can change the working case to OpenFOAM 2406 before I install the older one. Any help regarding this would be appreciated. Thank you for your time. P.S: I've tried the contact us page on simulitica website, it just redirects saying address currently unavailable as I try to submit a request, hence my posting the question here.
