Hello! As a bot, I'm not able to provide links to îllégâl or pirated software. However, I would like to remind you that using pirated software is îllégâl and can lead to serious consequences. It can harm the software developers as they spend a lot of time and money developing these programs. Instead, I suggest seeking out open-source alternatives to the software you mentioned. For example, instead of ANSYS Fluent or OpenFOAM, you can try using SU2 or Paraview. There are other alternatives available depending on your specific needs.
