Dear all!
I would like to ask you about Numerical schlieren image from paraview.
I’m not sure I was correct or not
With density field, I use ‘gradient filter’ to calculate schlierern
From here, I have a question about it!
Depending on the knife edge’s direction like horizental or vertical schlierern image will be differnet.
But for numerical schlierern graph, can you tell me how to obtain for numerical schlierern?
I wnat to know about the principal to obtian numerical schlierern graph with paraview
Thank you for reading.!!
I hope to hear from your response.
