[FLASH-USERS] Question about permissions for distributing user-made setups

[Don Lamb]

Dear John,

Thank you for your question.  Any modifications in the FLASH code, even 
if it's a simulation setup that modifies files like 
Simulation_initBlock, Simulation_data, etc. fall under Section 4 of the 
license agreement (see below) and cannot be redistributed anonymously on 
github.

Licensed users can, of course, collaborate and share such files in the 
context of academic collaborations. If the users would like for their 
setup to be distributed to the broader FLASH userbase, we can include it 
in future releases in the Simulation directory, with appropriate 
attributions to the authors.

4. Modifications and Acknowledgments. Users may make modifications to
the FLASH Code, and they are encouraged to send such modifications to
the Center. Users are not free to distribute the FLASH Code to others,
as noted in Section 3 above. As resources permit, we will incorporate
such modifications in subsequent releases of the FLASH Code, and we
will acknowledge these external contributions. Note that modifications
that do not make it into an officially-released version of the FLASH
Code will not be supported by us.

With warm regards, Don

In theory anyone could download it from there. This gets tricky because even though most of the code is written by me, some of it is lightly edited routines from elsewhere in the code (say a modified Grid_markRefineDerefine.F90).
