Hi,

I have some issues that the image of volume rendering shows artificial lines

It looks that the lines are produced by misalignment between parent and child grid. 
Check this image with grid,

I'd like to figure out why this happens: whether it is caused by some bugs or I missed any options while load the FLASH data.

The slice-plot shows also some NAN regions,

I think it happens with same reason.

Thanks,
