<div class=""><br class="">
</div>
<div class="">Thank you for your prompt response. </div>
<div class=""><br class="">
</div>
<div class="">Sure, you can find attached a stripped out version of the main. I only have inherited that code, not developed it myself. </div>

<div class="">You’ll see that the same path to the dgf file is passed to all MPI ranks but I don’t understand why initialising the DGFGridFactory is rank dependent.</div>
<div class=""><br class="">
</div>
<div class="">Besides, any comments/suggestions on the code are very welcome. Part of my job is also to refactor it for a better use. The main issue is that there is such a gap between Dune2.3 and Dune2.6 which makes it uneasy to track (owing that I have never
used Dune before :)</div>

<div class="">Hi,<br class="">
<br class="">
would you mind to share your setup code for the grid?<br class="">

<br class="">
I am currently working on a project to update a home made Dune module (peits) to the newest Dune modules. Peits was previously running fine with Dune modules (common, fem, grid, alugrid, geometry) v2.3.<br class="">
<br class="">
Now I am trying to update to the same Dune modules v2.6. I have managed to compile (under GNU compiler) and run serially Peits with Dune2.6 but the issue appears when I run in parallel using MPI. This occurs when the gridPtr is called,<br class="">
<br class="">
And trying to create the grid from a dgf file, especially the assertion:<br class="">
<br class="">
<a href="https://gitlab.dune-project.org/core/dune-grid/blob/master/dune/grid/io/file/dgfparser/gridptr.hh#L281" class="">https://gitlab.dune-project.org/core/dune-grid/blob/master/dune/grid/io/file/dgfparser/gridptr.hh#L281</a><br class="">
<br class="">
Basically, what I have narrowed down is:<br class="">
<br class="">
<br class="">
* The MPI rank 0 runs fine. It fetches all parameters from files, calls the DGFGridFactory, initializes it etc.<br class="">
* The MPI rank 1 comes to the same point but I have checked that the initialisation of the DGFGridFactory is not setting the necessary parameters the same way, I.e. the elParam_ size is set to 0 (whereas ~57000 in MPI rank 0) causing the above assertion
to fail.<br class="">
<br class="">
I wanted to know if there is a dedicated procedure to create a grid in parallel which I am missing at this point. Could you advise on this issue ?<br class="">
<br class="">
That would be really helpful.<br class="">
<br class="">
Kind regards,<br class="">
