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?

Yesterday, we had the pleasure of welcoming Professor Hrvoje Jasak from the University of Cambridge to UFRJ's Escola de Química for a lecture designed for new postgraduate students. He told about the journey of Computational Fluid Dynamics (CFD), including its history and exciting industrial applications. It was a great session that helped both postgraduate and undergraduate students to know this fascinating area of engineering. The lecture was recorded and is available in the following link: https://www.youtube.com/watch?v=AmBzIKPxlGU&list=PLlLNIDf07yx_dOFbNppMj-zutAxkiBG__&ab_channel=EscoladeQu%C3%ADmica .

On September 23rd at 12:00 pm, we will have the honor of welcoming Professor Hrvoje Jasak to the UFRJ Escola de Química for an interesting lecture on general aspects of computational fluid dynamics (CFD) for newcomer EPQB students. Professor Jasak, a co-creator of OpenFOAM and a faculty member at the University of Cambridge, earned his PhD from Imperial College. He has also worked on other popular CFD softwares like Ansys Fluent. His insights will definitely enrich your understanding of the field. Don’t miss out! The lecture will be in room E-212 at UFRJ and will also be streamed live. Stay tuned for the link! https://youtube.com/live/AmBzIKPxlGU?feature=share . Join us!

Hello everyone. I recently took the initiative to create my laboratory's social networks. We are starting our posts and we will try to bring relevant topics to promote good scientific discussions. Today we are posting a little about our experience with the experimental PIV and Shadow Sizing techniques. Come and learn a little more about us and, if you like, like and follow us to receive our posts. The post link: https://www.linkedin.com/posts/labcfd-ufrj_piv-activity-7237938870183464961-tlsQ?utm_source=share&utm_medium=member_desktop Hugs to all!

Hi everybody! Happy to have you all here and very excited to kick-start a long journey of mentorship and growth with all of you. To help get to know each other and break the shyness, take a moment to introduce yourself below and let others know what you're currently working on (CFD or in general). ** Please make sure you have carefully read this post and participated in this poll [takes 5 seconds] Let's go!
