acusolve configuration file and pdir
Hi guys,
I have two simulations. Second simulation folder is inside the first folder.
%%%%%%%%%%%%%%%%% FIRST %%%%%%%%%%%%%%%%%%%%%
I have a configuration file, Acusim.cnf with
Location: /home/user/simulation
# date = Fri Nov 4 13:33:04 2022
problem = test
problem_directory = /home/user/simulation
working_directory = ACUSIM.DIR
process_modules = all
input_file = _auto
message_passing_type = impi
num_processors = 24
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%% SECOND %%%%%%%%%%%%%%%%%%%
Location: /home/user/simulation/inside
# date = Fri Nov 4 13:33:04 2022
problem = test
problem_directory = /home/user/simulation/
working_directory = ACUSIM.DIR
process_modules = all
input_file = _auto
message_passing_type = impi
num_processors = 24
But I call acusolve from terminal with command: acuRun -pdir /home/user/simulation/inside
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
I mean the two problems have same configuration file. Except that i call first problem with terminal command acuRun -pdir /home/user/simulation and second problem with terminal command acuRun -pdir /home/user/simulation/inside.
Are these simulations solving same problem or different problem? Does specifying flag -pdir -np in acuRun terminal command neglect/override what is written in the configuration file?
Thanks!

The command-line takes precedence over the Acusim.cnf file. When in doubt:
acuRun -pdir /home/user/simulation/inside -h
will give all the options for acuRun, including where it's getting the information (command-line, Acusim.cnf, default, etc)
Thanks! This is really helpful!
If i want to run simulation in second folder (which is inside the first folder) from the first folder, I use acuRun -pdir /home/user/simulation/inside.
But the first folder already contains acusim.cnf file. Which simulation is it running? Which geometry file, mesh.dir are being used? The one in first folder or the second one?

This is the link to the AcuRun program - with some explanation of options.

You have problem directory (likely where the .inp and MESH.DIR reside) and working directory (where runtime and results files reside). You want to pay attention to both when working with/from/to embedded directories.
My suggestion would be to make some noticeable differences in the input files, and test the response.
At the bottom of acuRun -h you'll see the locations where it looks for Acusim.cnf files - based on the directory where acuRun is issued. Unless you modify the environment variable ACUSIM_CNF_FILES it will ignore Acusim.cnf file in other locations.
