How to import a mesh into Microsoft Azure notebook

9 months ago by
I'm working with the demo at I would like to import a mesh that is on the hard drive into the notebook. Is it possible to do this?

The mesh is in h5 format. So currently, you can run a script and import the mesh using:

f = HDF5File(mpi_comm_world(), 'mesh.h5', 'r')
mesh = Mesh(), 'mesh', False)

I'd like to do this in an Azure notebook. Any help doing this would be greatly appreciated.

Thank you,

It should be possible - although of course, Azure Notebooks are not very powerful, so don't expect to solve huge problems.

There is a "data" dropdown menu when you are in a notebook - you should be able to use that to upload a "h5" file (and any other file)
Thank you for replying - that worked!

Are there any cloud computing options that run FEniCS that are more powerful than Azure? I would like to import a 3D mesh with 2 million cells, that forms a 9.4 million dof linear system, and my laptop takes 4 min per iteration, which is too long

What's the equation you're solving and which solver are you applying to the linear system? That seems very efficient being able to solve a system that large and that quickly on a laptop.

I'm solving the advection diffusion equation, with velocities computed from the Navier Stokes equation. The solver for the linear system is GMRES, with the ILU pre-conditioner. I need to run about 30,000 iterations, each time step size is 0.001 second
