Subject: [Paraview] AMR and .VTM<br>
<div class="im"><br>
Dear all,<br>
<br>
I had a rather quick question. I am working with adaptive meshes and would like to import them into paraview. So far I have been able to that with unstructured datasets and .vtk files. The problem is that whenever I use slice filter to see a cross-section of mesh, it triangulates the dataset and I see triangles instead of blocks (I'm using Cartesian AMR). I was wondering if this can be solved by using multiblock datasets and .vtm format. If so, can anyone please lead me to a good tutorial on .vtm format? It seems I cannot find a good one.<br>
<br>

I do not know of any tutorial on AMR data for ParaView. But I can confirm that the support for patch-based AMR works very well.<br>
Are you using your own code, or a standard code such as FLASH, Enzo,..,?<br>
<br>
You should start by running an example from Sources. Use Hierarchical Fractal, save it to disk and look at the output: It will look like that:<br>
<br>
<VTKFile type="vtkHierarchicalBoxDataSet" version="1.0" byte_order="LittleEndian"><br>
<vtkHierarchicalBoxDataSet><br>
<Block level="0" refinement_ratio="0"><br>
<br>
</Block><br>
<Block level="1" refinement_ratio="0"><br>
<DataSet index="0" amr_box="0 9 0 9 0 0" dimensionality="2" file="foo/foo_0.vti"><br>
<br>
etc..<br>
<br>
For each level, the patch's index start at 0, the amr_box is the extents of the grid in number of cells with respect to the current level.<br>
There is a VTK API to write ImageFile data (*.vti files). You might want to use that, and then write the wrapper code assembling all the patches from your own program.<br>
