Dear Foamers,

I have successfully built OFV1912 on an arm device and I was able to run elbow, pitzDaily, airFOIL2D, simpleCar and rotorDisk. Its only when running the Allmake for MotorBike that I run into a problem. The allmake script runs to fast and when I use paraFoam to view results, paraview only shows solid body, no values for P, U, Nu, etc.

I checked the logs and it just shows a warning saying mpirun as root is not recommend. I assume its due to mpi on my device (which is an android phone running ubuntu 19.10 via a container). Is there away to run this tutorial without mpi? The case runs fine on my x86 device so I know its a mpi issue.

Don't run it in parallel? Or do not try to run anything which requires root access?

My container logs me into a root account so whatever I do is root, i still haven't figured out how to create a working user account in the container.

Also when running any parallel cause I get this error warning:
Code:
[localhost:31131] opal_ifinit: ioctl(SIOCGIFHWADDR) failed with errno=13
So its definitely an mpi issue, I checked other parallel cases as well. Is there any serial equivalent to motorbike? Or how would I make it run in serial?

Hi,

- Have you installed OpenFOAM in root or your user area?

Hi,

- I am still not sure, since it seems that you have made the installation to the root area. Hope you find solution.
