Hello everyone:
I used the case (fluid_bed_dem_2d) implemented in the mfix tutorials to test the dmp in the mfix-22.2.2. the operating system is centos.
the dmp solver can be build successful, however, when run the solver, the following error occurred:
Note, I changed the topic subject line to be more specific.
What is your CentOS version? You made a .zip file of the project directory instead of using “Submit bug report” from the main menu, so the system information is not generated, and a lot of unnecessary files (the build subdir) are included. In the future, please use “Submit bug report”.
What DMP domain decomposition are you running with? The .mfx file you attached has nodesi = nodesj = nodesk = 1
It’s possible that the problem is due to stack size limitations as described in this post:
Do you get a core dump? What is the output of ulimit -a ?
Hi, cgw, thank you for your answer.
I used the command line in a HPC, there isn’t a GUI, so which command should I use to get the “sbumit bug report” —.zip file?
Hi, cgw, can you help me,please?
I really need your help!!!
“Submit bug report” is not available from the command line - sorry.
Please see the Stack Overvlow link I posted, and send the output of ulimit -a as I asked.
Hi cgw, I checked the HPC rencently, but I still don’t know the reason about the “segmentation fault”.
the output of ulimit -a is as follows:
and to build the mfix-solver, I used the command:
(mfix-22.2.2) [songchao@cu01 fluid_bed_dem_2d-5]$ build_mfixsolver --batch --dmp -j 10
to run the case, I used the command:
(mfix-22.2.2) [songchao@cu01 fluid_bed_dem_2d-5]$ mpirun -np 2 ./mfixsolver -f fluid_bed_dem_2d.mfx
First, we need to rule out any setting error. Please provide your DMP domain decomposition.
What happens if you do
mpirun -np 2 ./mfixsolver -f fluid_bed_dem_2d.mfx NODESJ=2
