Hi,
i am simulating the flow over an airfoil, i use sapalartAllmaras turbulence model, and simpleFoam solver, after 473 iterate it give me this error and exit the iteration after that : Getting LinuxMem: [Errno 2] No such file or directory: '/proc/9170/status' what should i do, please give me some guidance Code:

Greetings s.m,
A few questions:
Best regards, Bruno PS: please follow the instructions on the second link of my signature, for whenever you need to post output from solvers or utilities, or source code!

2. no i didn't run openFoam's tutorial to get this error 3. i am using the "forceCoeffs" function for expressing the cd&cl on airfoil 4. my case' volume is too large 5. no i didn't run my case in parallel. i change my opensuse several time, but this problem is still annoying me, and my run stops every 500 steps approximately after giving this error. Thank you for spending your time to solve my problem

Hi s.m,
My suggestion is to either install OpenFOAM 2.2.1 or 2.2.x, because I've got a feeling that what you are seeing is a bug that has already been fixed in the latest OpenFOAM versions. If you could adapt an existing OpenFOAM tutorial case to use the same kind of simulation characteristics that your case is using, and if that test case were to give the same error, then you could share that test case and I could confirm if this is a bug in OpenFOAM 2.2.0 that has already been fixed or not. Either way, from what I can see, there are at least two ways you can install OpenFOAM 2.2.1:
