VTKHDF format


I have two VTKHDF dataset, one with the full flowfield and one with only surface data, is there a way to combine those dataset into one VTKHDF? If so, can this be done also at writing time? What should be the VTKHDF file structure to achieve that?

Best regards


Hello @Frankx9,

What datatype are you using for these 2 vtkhdf file? PolyData? UnstructuredGrid?

We actively work on extending the VTKHDF file format to have composite data set, the design proposal is here:

So when it will be done, the best way to handle your use case will be to use it.


Iā€™m using unstructured grids at the moment

ok, so the best way still be to use the future composite support in vtkhdf file format which will contained your 2 UnstruturedGrid.

I will keep you up to date about any improvement in vtkhdf file format regarding your use case
