[Qgis-user] mdal / mesh simple formats

[Matt Boyd]

Hi Peter,
woohoo, awesome, okay now I get it and it works.
I thought that as the 2dm file had duplicates of the cells & nodes in
the simple mesh I was looking at that it wasn't needed. Also the xdmf
loads directly into paraview so I thought that QGIS would do the same
thing.
All I need to do is generate a 2dm file with nodes and cells like the
examples and my meshes *should work, easy.

Thanks again, I'll post this back to QGIS users in case anyone else
hits the same issue.
Matt

So in that menu you need to load 2dm file == definition of your mesh frame, and once loaded, you right-click on the mesh layer and "add values/datasets" in the properties (XMDF) file. Some files (e.g. netcdf) has it in one file all, but this one is different.  Best to check some online tutorials.
