Subject: [Hdf-forum] Irregular 2D array write (C++)
So I'm wondering if there is a good way to write an irregular shaped 2D array
into hdf5. And example of this would be like storing vtk node connections for
an unstructured grid. First number noting the cell
We actually do this exact operation for our project. What I decided to
do was to first flatten from a "vector of vectors" into a single array,
then write that array as a "normal" array to HDF5. Add an attribute to
the HDF5 dataset to state what the array represents so that when you
read it back
Your corresponding C++ type for this array would be
std::vector>
such as for storing cells in mixed meshes, like quads and triangles mixed?
If so, you need a variable-length array data type of type integer, i.e.,
HDF5 will see it as
vector
It's not overly efficient to use variable-length da

Hi Steven,
Hmm. I am thinking maybe a few approaches.

Hi Steven,
Would variable-length datatype do what you need?
