I try to run a transient particle simulation and sample at the outlet several times with a journal file as given below in Fluent. My final aim is to have several sample files (.dpm) at the end. To this end, I used the do-loop but I couldn't make it work. However, without using the do function, the code works fine for one simulation run. <\/p>\n

I have two questions: <\/p>\n

1) How can I make this code work? When I run this code, first I get the warning "Warning: An error or interrupt occurred while reading the journal file. Some commands may not have been completed." on Fluent GUI and then "Error: eof inside list, Error Object: ()" in the console.<\/p>\n

2) I want to change the dpm sample file which is generated automatically by Fluent, when I run the "\/report\/dpm-sample" command in the last row. How can I change the file name for each trial in the loop below? For example: outlet_1.dpm, outlet_2.dpm etc.,.. I looked through the TUI command list, but the commands to write a file are related with data case files.<\/p>\n

Thank you in advance,<\/p>\n
