test field -> modify components/coordinates -> viewer 3D
Choose all 2D components in test field. In modify components/coordinates go to the mask tab.
There are components in the mask drop down menu, which do not make sense/do not work appropriately: byte data, complex, logic.
In the menu there are not included vector components but could be included.
Time data - probably the first time step - may be there should be some information?
Choosing x_coord as mask data, after pressing the run button null appears in the menu, however, data seem to be masked.
It seems to me that masking in this module worked better a few years ago.
