I tried to modified the Makefile.inc like belowed

#CXX := g++
#CXX := icpc -D__aligned__=ignored
#CXX := mpiCC
CXX := mpic++
…….
#PARALLEL_MODE := OFF
PARALLEL_MODE := MPI
#PARALLEL_MODE := OMP
#PARALLEL_MODE := HYBRID

and made it again. But it didn’t work. The pvd file was still bad.

Dear albert.min-k,
I’d love to. I agree with you that it may be my MPI’s fault. I have tried OpenLB1.1. The fault still existed.
Would you mind telling me how can I post the Makefile.inc in the OpenLB project?

[steed188]

Dear Marc,
I’m happy that you focused on my question.
I’m new in LBM, trying SmagorinskyBGKdynamics for high Reynolds numbers flow in outdoor wind environment. Yeah, it is very important to get time averaged velocity. If there is no functor in OpenLB, I hope to develop it maybe later for I have to take some time to be familiar with OpenLB firstly. Let’s work on it together if you would like to.

Best,
steed188

Dear albert.min-k,
Thank you so much for your focus on my question.
When I execute sequential, the pvd file is correct. But when I excute Parellel, the file is wrong. I seems like that the processors scrambled to write the vti files in the pvd file with out an order sequencing, leading the file fault.
And I can’t open the wrong pvd file with web browser, showing error.
Regards,
steed188

And I am using OpenLB 1.0, in the platform of CentOS linux 7.3.1611 with OpenMPI 1.6.3
