Some issues on MultiApp usage

[庄坤]

Hi,

Much thanks to your development of moltres code, it is an excellent code for analysis of molten salt reactor. Recently, some problems bother me when I learn how to use it. I hope you give me some advices.

I want to simulate a simple core to get keff, flux and precursors distribution in active core and external loop. This simple core consists only one MSRE-like fuel channel, and the external loop has the same geometry but without graphite reflector. Thus, precursors decay in the whole primary loop and have no source in external loop. I used <MultiApp> to couple simulation between in core and in external loop.

The attached file is my input card for Moltres, and it run normally, but it seems that the data is not transfered correctly (the outlet of precursors in  'dnp_flow_core_and_external_loop.i' are not transfered to the inlet of precursors in 'dnp in external loop'). I have made many attempts, but it still doesn't work. I don't know where the problem is, and  I wish you help me.

Any suggestions would be appreciated.

Looking forward to your reply.

Best wishes,

Kun Zhuang
