Create a region into an output file and visualizing it in Paraview

Hello,

So I am creating a region to measure the average velocity at a particular location. It is a block that uses the move and rotation arguments so I feel that it could be very easy to input a wrong value, especially if my input is a time function. I cannot seem to find a way to create a file with this region data so I can superimpose it in Paraview and visually confirm that it is at the right location.

I know I can create a .vtk file with my initial region with a create_box command. However, through my attempts it does not seem possible to use this command twice in a single input file.

When I use mesh/surface fix on an .stl plane, I know I have the capability of outputting a .stl file of this plane. However, I cannot figure out an equivalent way of doing this for regions.

So far the best thing I can think of is creating a second input file, remove all the geometry, change the insertion location, and switch out my simulation region with my region for checking velocity. This would create a .vtk file and then I could just superimpose the two simulations over top of each in Paraview to confirm that the data I am collecting is at the right location. However, this is extremely convoluted and if I am not careful I could forget to alter both files.

There has to be a way of outputting regions into a file format so it can be visible in Paraview. Without this sort of check , I could imagine it would be very easy to make a mistake and collect the wrong data without a clue that it is wrong.

Thanks,
Anthony
