      hi all,

      what's the hell beetween standard initialisation and hybrid initialisation ?

      regards charly

      Hello,
       
      Standard initialization takes the values defined by the user for the solution variables and initializes the flow field to these values. This is the recommended approach for advanced simulations such as those involving porous media. 
       
      Hybrid on the other hand, provides a slightly more realistic approach by imposing a non-uniform initial guess. In this method, a Laplace equation is solved to determine the velocity and pressure fields, and all other variables are automatically patched, based on domain-averaged values or a predetermined interpolation approach. This is the default initialization method in Ansys Fluent and works well for a wide range of problems.

      Make sure you follow the 1st step before pasting the link.

      1. First open the help section of Ansys through the software ( ? button on the upper-right side of the Fluent Solver User Interface: This opens help in a browser)
