when I load the state file test.pvsm using the PV4.01 binary I get this

But when I import the file, I can only apply Table To Structured Grid filter, and it reads the file as if it were arbitrary curvilinear grid. How can I transform this grid to the rectilinear one? And is there any way to interpolate data between points, as grid size is 12*11*14 only? I could, for example, create finer uniform rectilinear mesh and estimate f on this mesh points, then plot it, but don't know how to do it. Any advice is appreciated.
