Problem on succesive simulation runs and dpm file naming

I try to run a transient particle simulation and sample particles 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.
I have two questions: 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. 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. Thank you in advance, Journal File: Code:
(define numbOfIterations 2); Define number of max. iterations per time step (define delta_t 0.06); Define time step size [s] (define no_t_s 2); Number of time steps (do ((x1 1 (+ x1 1))) ((> x1 3)) ; define count - variable , start value and increment, define stop condition /solve/initialize/initialize-flow y y ; do the Initialization, y y to discard the old data and clear history /report/dpm-sample injection-0 injection-1 () outlet () () n n ; start sampling /solve/set/time-step delta_t ; set the time step /solve/dual-time-iterate no_t_s numbOfIterations; Perform unsteady iterations for a specified number of time steps /report/dpm-sample ); |
