How to export the calculated data after successful simulation. For example, if I want the velocity value for each coordinate, how can I derive it
You can use the "Export Results..." > "CSV Format..." option from the "Post" menu to export the current data (in the current plot) in the mesh points.
If you have specific points or more complex expressions, it is best to export the data to the command line and use the "evalexpr" function as described in the documentation:
