  5. Amazing work. this calculix louncher. free the mecanical engineer of the monopoliy of overpriced Proprietary software like ansys or simens.

    1. This is not 100% true. If you need to solve little problem, that is not typical for you (for example thermal analysis at structural engineering) - you don't need to buy full Ansys or Nastran for that (which can be more expensive than you current order). But if you're doing structural work every day - you will need professional software. Free software is the supplement and not a replacement

  6. there is more, if programming becomes like pharmacy today, its bad. some one has a problem and want to do some engineering and he can only go to the software companies which sell at high prices, that is bad. think about, poor country's where a engineer wants to solve complex problems.
    And also copying data doesn't cost, so why do those company's do ask ridiculous prices.
    PS: last video of ball and plate. super! want to try it my self
