Boundary condition at the corner of square cavity

      Hi,

      i try to simulate a natural convection in square cavity by using hyperbolic mesh on ICEM.

      the lenght cavity is 0.3m . i run the programme it works.

      • when i opened the file that contain the export data of my configuration, i am surprised !!! the last value of x coordinate wa 0.3000000119 ?? while i imposed L=0.3 m.

      Round off errors might happen. How did you do the export sbd what do you mean with the hyperbolic mesh? What dies ICEM CFD tell sbout mesh extents?

      thanks Dr Amine for answing.
      for exporting solution data : i clicked on file ->export->solution data -> file type : ascii ->location: noeuds->surfaces: fluid-> quantities

      ii used yperbolic mesh law on ICEM :hyperbolic distribution of the nodes along the edge (i attached a picture for expression and you can see on the ICEM-HELP-MANUAL P481

      What does the software report about the mesh extents?

      what do you mean by 'mesh extents'? the passage from ICEM to ANSYS ???

      What does ICEM CFD report for the domain extents? Did you open Fluent in double precision?
