[Nek5000-users] Conj HT problem w/ latest repo

Thu Jun 24 11:01:30 CDT 2010

Hi, 

I am having a problem running a conjugate heat transfer test case. I was able to get it to run with no problems on the repo I had (which I checked to be early 400's, 410 I believe, around April). 

I checked out the latest repo version and am now getting NaN values for Helmhotlz VEL X, Y, & Z. A few lines are shown below for Step 1. I have attached my case file. I am not sure what the issue is, nothing has changed other than the repo version I am now using. Thanks for any help.
