It was quite interesting.</p> https://akenji3.github.io/en/post/20250106_cavity/ Mon, 06 Jan 2025 00:00:00 +0000 https://akenji3.github.io/en/post/20250106_cavity/ <h2 id="introduction">Introduction</h2> <p>Yesterday, I installed OpenFOAM and ParaView and tried to simulate and visualize a Poiseuille flow (Hagen-poiseuille flow). This time, I followed the book and ran &ldquo;cavity&rdquo; from the OpenFOAM built-in tutorial.</p> https://akenji3.github.io/en/post/20250105_openfoam/ Sun, 05 Jan 2025 00:00:00 +0000 https://akenji3.github.io/en/post/20250105_openfoam/ <h2 id="motivation">Motivation</h2> <p>I have been working on PINNs since the end of last year and have attempted two problems. I am planning to select and work on problems in the field of fluid dynamics. In fact, I am working on incompressible flow around a cylinder, but I have been stuck for a week because I can&rsquo;t figure out how to relate the output of the model to the differential equations (the key part of PINNs).</p> <p>I decided to learn a bit of OpenFOAM if I am going to work on the fluid dynamics area, so I installed OpenFOAM, ParaView, and tried the examples.</p>
