I have a block based AMR code which outputs cell centered coordinates and values. I made some initial attempts to convert that into a multi-block output (*.vtm),
However, the problem is that ParaView cannot figure out the connection between blocks, so there is a gap in between:
I am wondering what is a proper way to handle the data. Should I switch to the original node grid, or do some trick to let ParaView know the blocks are connected so that common filter can work?
If you want common filters to work on your data set, you can use the MergeBlock filter to append all blocks in a single data set.
Notice that this filter wont “glue” your blocks. Do you also need blocks to be merged in terms of neighborhood ?
I was just about to make a post with a similar issue. I have a multiblock terrain representation that I’d like to run some contour and volume simulations over. However, like henry2004y when I import the plot3D .xyz files there’s a distinguishable gap between the blocks (see attached picture).
I’d like to find a way to eliminate those gaps to allow for smooth animations at the block boundaries.
I’m thinking this has something to do with ghosting variables, but I’d appreciate someone’s insight into the problem!
Yes. The blocks should be merged, but simply with the merge block filter, I can apply common filters, but the gaps are still there. And also using the merge block filter converts the structured grid to unstructured grid, which is what I want to avoid actually.
Can you provide an example as to how to make a connection between the blocks? I tried the GroupDatasets filter followed by the Merge Blocks filter, but still cannot get Paraview to remove the space between blocks.
