The answer to your question depends on a lot of things. I’ll start by assuming that your data looks like that in another post you recently commented on ([Paraview unable to render World Ocean Atlas NetCDF files](https://discourse.paraview.org/t/paraview-unable-to-render-world-ocean-atlas-netcdf-files/2757/4)), and that your data is in the CF convention and uses structured data.

In this case, to load the data as a rectilinear grid, uncheck the `Spherical Coordinates` option (preferably before the first `Apply`). This will load the data as either a rectilinear grid or an image (i.e. a uniform rectilinear grid). However, you cannot directly render a rectilinear grid in ParaView. To force loading the data as a uniform rectilinear grid that can be directly volume rendered, you can also change the `Output Type` to `Image`. You may get a warning stating that the `OutputType` cannot fully represent the data. This is because the netCDF defines the coordinates with uneven spacing, which cannot be represented with data that has uniform spacing.
