Morning all,
Sorry, this is a repost, I posted this in the Mesh Utilities forum sometime early last week and haven't received any responses. I thought perhaps this is a better forum to post it, where it might be seen. Anyhow, on to my problem. I've run into a requiring problem that I can't seem to fix. So, I thought I'd bring the problem here and see if anyone has some familiarity with it or any insight. Additionally, I've posted the problem on collab.pitt.edu. The problem I'm having involves using the mapFields utility on a supercomputing cluster, SAM at Pitt. When I run locally, the utility has no problems. However, when I run on the cluster, the utility likes to create "nan" entries in the pressure fields. The problem then being, when I run my solver, simpleFoam in my case, errors occur when the first "nan" entry is encountered. I get the error: Quote:
From what I've been able to gather, the reason I only have this problem on the cluster could be due to a discrepancy between the $FOAM_SETNAN entry I have locally and on the cluster, however, when I checked the setting on both, they were the same. As of this point, I am unsure what exactly I should do. I have previously just run mapFields locally and then uploaded the newly initialized time to SAM. However, this isn't a convenient way to do it, and will be extremely time consuming in the future when I have larger, more intensive simulations. Any help or suggestions? -Tyler Last edited by tlandfried; August 3, 2012 at 14:55. |
