Hi G Rigon,
<div class=""><br class="">
</div>
<div class="">Yes, this is doable by calling the subroutine IO_setScalar. You could call this subroutine in the file Simulation_sendOutputData.F90. It might be helpful to look at Driver_sendOutputData.F90 as an example, where the “time” and “step number” are
outputted to check / plot files.</div>

</div>
<div class="">In addition, just a reminder that since it’s a global variable, any change on a local processor needs to be MPI-broadcasted when necessary.</div>

<div class="">Hope this helps!<br class="">

<div class="">Hi,<br class="">
<br class="">
I would like to create a global variable for my FLASH simulations. By "global variable", I mean a variable which can be written in the output file (plotfile) and which hold the same value for the whole grid. Typically it will be a variable similar to the "time"
or the "step number". I don't want to create a variable defined on the grid (such as the density, velocity...).<br class="">
<br class="">
Is there a simple way to declare such variable (for instance in the Config file)?<br class="">
<br class="">
Best regards,<br class="">
G Rigon<br class="">
