Good Information sir

[@user-mw6ej1lc7o]

Thank you

[@user-mw6ej1lc7o]

Can you please make a video of the Grid Convergence Method?

[@dr.venkys-easylearningknow915]

Sure

[@mounarahal256]

for independency test, should i have the same type of meshing (hexa, tetra,..) in the different parts or i can do it if i have two different meshingd at the same time(hexa+tetra).

[@dr.venkys-easylearningknow915]

You can use both hexa and tetra. But the output result should be same for coarse, medium and fine cells. This is the condition. Also refinement ratio should be greater than 1.3.

@@dr.venkys-easylearningknow915 thanks but i don't understand the output result? what is it? and also to understand be precisely, for example if i have a rectangular plate (part1) meshed with tetra cells and it is circulated with a tube (part2) which is mesh with hexa mesh, should i dp the independency test at the same time for the two parts or i do them independently?
and for the refinement ratio you mean at each part with different mesh i should have 1.3?

Sir if velocity value for coarse,medium and fine is different then which mesh to be chosen

[@dr.venkys-easylearningknow915]

Always select fine mesh

[@jillebit8105]

But in this scenario you can't be sure that your finest mesh was fine enough, because further refinement could still have an impact. So, I guess you should test with further refined meshes and check if the output results indeed are not dependent on the mesh.
