Do you want to learn about Fluid-Structure Interaction along with simulations in #openfoam? Then, this course is for you. Almost one year of hard work finally took shape. Very excited to announce the online course on FSI in collaboration with 1/

@laurencemarks64 Can't imagine doing this properly with Abaqus or any other commercial software.

@batatalal My own code for hierarchical b-splines from a decade ago. I will probably move to p4est in the future.

@yungyuc Dictated by the solver. This can be done with unstructured grids as well but some methods (and solvers) are easier to implement on Cartesian grids.

@yungyuc Uniform b-splines are easy to implement. A couple of weeks of effort is sufficient. The hierarchical part took most of the time. Needed to implement quad and oct-trees (in C++).

@yungyuc Indeed! It took me over 6 months to develop hierarchical b-spline grids for my post-doc project during 2013-2014.

The indiscriminate and ill-conceived slashing of indirects by the @NIH yesterday must be amended if want to restore America’s leadership role biomedical research. 15% simply isn’t enough for institutions to provide the basic infrastructure needed to run a successful lab. I say this as someone who has been and remains deeply critical of the NIH, its funding system and of the ways universities are structured and spend money. We would all benefit from a genuine reexamination of how and to what @NIH funds are allocated, and I remain optimistic that once the dust settles and new NIH leadership is in place that this is what will happen and this hack job by people who don’t understand or care about research will be forgotten. And I’m sorry but I can’t help but laugh at the people who are demanding a full-throated defense of the current indirect levels. Nearly every PI I’ve known for my entire career has complained about excessive indirect rates. This is mostly because, despite their importance, even most PIs haven’t bothered to actually understand them, and because they don’t FEEL that universities are actually spending the money to support their research. Whether they are or not nobody really knows because in the typically Byzantine maze of university budgets it’s often very hard to figure out. There are also lots of actual shenanigans that go on especially at places with the highest indirect rates to use funds to build out the institution and increase its power rather than to directly support funded research projects. And anyone who says administrative bloat at universities isn’t real and partially fueled by indirects is either blind or part of the bloat. So let’s get organized to have an actual constructive response to this firebomb. Scientists need to advocate for what is best for research - and we have to do it ourselves because the institutions that claim to represent us - universities and scientific societies in particular - have their own goals that often do not align with ours. We also have to remember that grants are not an entitlement. We are not owed anything. If we want to continue benefiting from the public support we have always enjoyed, we have to show the public and their representatives - even ones we might not always agree with - that we’re spending their money wisely.

They keep pushing it forever 😂 There are only ways to achieve #NetZeroaviation. 1. We evolve to fly. 2. We stop using planes for transport.

LOL. @AnthropicAI's Claude AI achieved AGI. It implemented multiphase flows in the SU2 library. 😂

@yungyuc Thought so! Why don't you work on others' code when you know all those features and talk so much? Because you don't have time for it. That's what I am saying! Talk is cheap!

@yungyuc I see. If I share my code, would you change it using all those features and improve it? I can't pay you for it, though.

@yungyuc I am sure there are a lot of nice features like that. But it's all about what you knew when you started to develop the code. After some point, it becomes quite difficult to change it with the new programming features. The cost of learning new features & updating the code is huge.
