I want to simulate a particle inlet boundary with given solid volume fraction and velocity, i.e the solid volume fraction and velocity in this boudary region is always fixed. I defined a region above the boundary, calculated the massrate, and used the insert/rate/region command. Since I want to keep the solid volume fraction fixed, should I set the insert_every to be 1?
I found many warnings come out.

no, this is not efficient. You might find a good trade-off between accuracy and efficiency with something between 500 and 5000

thanks and tools recommanded
Thanks for the tips.
I want to get deep into the code about the insert boundary. However I donot familiar with the structure of code now, could you recommand some tools to help read the code, such as the IDE platforms ?

Massrate
I am running a simulation with fix insert/stream command. Following is the command in script.
fix insertion particles insert/stream seed 5330 distributiontemplate pdd1
& verbose yes maxattempt 100 mass INF massrate 1.0 start 1000 overlapcheck yes vel constant 0. 0. -1.0 & insertion_face inface extrude_length 0.4
I have assigned massrate = 1.0 but I really don't know how much actually it is. Simulation script is in SI units but from results I do not get mass insetion any way near to 1.0 kg/second or something like that. Please tell me how much actually it is.....
