The topology supported by unity is shown in the figure. Therefore, if the vtu file contains hexahedrons, can it not be displayed in unity?

You can use vtkExtractSurface to extract the outside shell of the volume and vtkTriangleFilter to change all cells to triangles. The resulting dataset will be compatible with what unity can display.
