open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all,

I am using the version of v8p2r0, and want to solve bedload and suspended load at the same time. but I meet with some difficulties:
Que (1): It seems that the keyword LIQUID BOUNDARIES FILE can only be add in the main steering file rather than the gaia steering, and I can use one liquid boundary file to indicate both how my liquid discharge and the input suspended-load concentration vary in time, but how to declare the time-series of bed-load discharge, is there a sample format in the above liquid boundary file? as shown:
T Q(1) QG(1,1) TR(1,2)
s m3/s m3/s kg/m3
0 714.0 0.01 0.080
86400 714.0 0.01 0.080

Que (2): The model has only a small number of grids (about 2000), and the steering file was not prompted for an error, but no results have ever been calculated. What may be the reason?

Please find the attachments.
Thanks in advance. Please help me.
