The core of our method is a new anisotropic Stokes model with a unified representation of solid, fluid and solid-fluid interface. The density-based topology optimization method allows new topologies automatically evolve during optimization

How to handle questions in a presentation? When I was a student, I always feel stressful during the Q&A session after my presentation. 😵‍💫 In many cases, I didn't know how to respond well and just froze up there! 🥶 Sharing some tips I learned from others. 🧵

Often students become less communicative when they struggle to get a project idea working. However, reaching out to advisors is particularly critical in these situations in order to find solutions. That's much more important than giving updates when everything is great and fine.
