Hi all,

I would like to export data imported from the Ensight Gold format into VTK (.vtk).

When I go to File > Save Data, Paraview proposes only to export via the VTK Multiblock format (.vtm).

Unfortunatelly, I need to import the exported data into a program which recognizes only .vtk files.

Any help would be very appreciated.

Best regards,

William

The solution:

Filters > Alphabetical > Merge Blocks



Best regards,

William

The "cherry on the cake" would be to export each blocks in a script without losing their name.

For the moment, I have the following code. I would like to adapt the output file name (here 'file-1.vtk') to the block name as visible in Paraview.

# Import the case
case = EnSightReader(CaseFileName=
'/path/to/file.case')

# Extract the first block
extractBlock1 = ExtractBlock(Input=case)
extractBlock1.BlockIndices = [1]

# Get the name of this block
# ????

# Make it exportable in VTK format
mergeBlocks1 = MergeBlocks(Input=extractBlock1)

# Export it
SaveData('/path/to/file-1.vtk', proxy=mergeBlocks1)
