I used to have a very simple preparation method for catalase crystal preparation but have lost it. Does anyone have a straightforward prep method for catalase crystals?
Hello, I'm working on simulating 3D VIV with ANSYS FLUENT. To start with easy point, I made the cylinder static, but Karman Vortex Street just didn't show up. The fluid domain was separated into...
