Hello,
I have a problem how to extract geographic coordinates from the solution pvtk file.
When I tried to perform the simulation using 3D box geometry, I could get cartesian coordinates using paraview, and I could convert them to geographic coordinates (because I converted input parameters from geographic coordinates to cartesian before the simulations, I could convert to geographic coordinates again).
However, I tried to simulate using 3D chunk, It needed r (radius), phi (longitude), theta (90-latitude). I expected that the coordinates of the simulation results were also r, phi, theta coordinates, but it wasn’t.
My questions are,
- What is the unit of velocity? (meters? degrees? or something else?)
- How can I get or convert the location of the points to geographic coordinates?
My domain is 3D chunk, 105-150E(longitude), 15-50N(latitude), and 0-660km (depth).
First one is an example of my locations of points in the VTK result file.
Second one is a part of the saved test result using paraview-save data menu.
(I tested it with very low viscosity material)
