There are really good free and open source research FEA & CFD codes available, like FEniCS, Moose, Nek5000, OpenFOAM, SU2 and more. However, being research codes they can be difficult to learn and sometimes even compile and get running,

I often nowadays find GNU GFortran the same speed or faster than Intel Fortan for FEM/CFD codes, while 10-15 years ago Intel Fortan was 10-20% faster in general. So these days I typically just recommend to go with GFortan which is easi

Very interested in LFortran, are there any benchmarks how it compares with respect to performance to GFortran or Intel Fortran?

Thank you for explaining, I will have to explore this further as this opens up a lot of interesting possibilities. I find it very impressive that you have managed to get virtually no perceptible loading time at all, for octave running on a

This is very interesting and would never have guessed that it is possible. I would love to read a more detailed write up how all this works (is everything bundled to a large blob for the octave interpreter for example?). Also is the a speci

I guess the thing is most people only use one solver, but at least when I was doing research it would be rare that two physics solvers based on different discretizations give exactly the same results (sometimes wildly different). So I would

Thanks for the honest feedback. I started building FEATool far too many years ago not getting anywhere in academia after too many postdocs, since it was the one thing I'm passionate about and good at and I felt was "missing"

Yes, I think the initial simulation definition/set up can be "easy", but once you get to parallel shared memory clusters it unfortunately have to be much more hands on. I had hoped to eventually not only allow running individ

Don't really know how this ended up on the front page now, but the overall "idea" that I have yet to find anyone else understand and believe in (even my old prof and colleagues don't seem to "get it"), is that:

The first versions were open source asking for funding by donations. Although I would have really liked for FEATool to be open source (and I think such as tool would be ideally suited as such), unfortunately not having any form of funding b

Very interesting, making simulations "easy and accessible" really resonates with me having spent far too many years single handedly trying to get traction for my "easy to use" engineering physics, FEA, and PDE ideas and

Sure. As you guys seem to plan to do, I also started with some Matlab based work from my PhD years and felt that would be the quickest and easiest way forward. I also made the bet that the Octave app GUI functionality (uixx functions) would

As someone whos has written a very large and complex toolbox in Matlab [1], and now rewriting in Python I would not recommend locking yourself in to Matlab/Mathworks. However, if you don't use any GUI functionality you might get a
