Hi Matthew,
Thanks for the info. Could you give a specific commit that I should rebuild
PETSc with ? I’m currently building with
commit=83593104eb216a023c00ab8a3f9897d55e531412'.

I’m in the process of planning a basic fluids code based on the lattice
Boltzmann method (LBM) and would like some input from the petsc user base. All
the computation in LBM is local, so parallelization is straightforward and can
be simply done in a threaded application; a simple google search
Hi,
I have a question about PetscViewerHDF5SetTimestep usage.
I have tried the following minimal example which tries to write a vector
twice to an hdf5 file and it fails with the error message shown below.
Example : https://pastebin.com/cAeZsUgA
Error :
writing vector in hdf5 to vector.dat

Hello,
thank you this seems to be a reasonable explanation.
I will try this for my "steady" phases.
I have also phases where my Neumann boundary conditions change with time (in my
real application, here I uses constant conditions), in this time I also need
the results at exact time points.

Correction.
Not exactly more like this
While t<2
t=TSGetTime
h=TSGetTimeStep
TSSetMaxTime(min(t+h,2)
TSSolve
t=TSGetTime
TSSetMaxTime(t+1e-3)
TSSolve
While t<10
t=TSGetTime
h=TSGetTimeStep
TSSetMaxTime(min(t+h,10)
TSSolve
@Hong
No
In this example yes.

Okay, so you start your integration with
