Terminal Error: FEM2ESH#82

I just migrated to 2013 and installed SP2.  I am trying to run a transient heat transfer analysis on a scenario that ran under 2012 earlier this week.  I do not know what to do to fix it.  Below is the log data:

It appears the problem is a part that I suppressed.  If I un-supress it, the model runs.  If it is suppressed I get the error.  The suppressed part is one of two heating elements.  I suppressed one to see the impact on the temperature profile if one element was "broken".  That worked on 2012 but not in 2013.  I will have to try something else.

Hi G.A.,

 

It can be hard to understand the log file, but if my "translation" is correct, the last two things that the software did are as follows:

  1. "Made total 3641 enabled MPCs" from the log file indicates that you are using "smart bonding" because the mesh does not match between some of the parts. If this is the source of the error, it could be that this routine does not recognize that the part is suppressed. If you or the software defined contact with the suppressed part, try to suppress or delete that contact. The contact pairs are listed in the  "Contact (Default: ssss)" of the browser.
  2. "Writing to ESH file in phase II (FEA objects)" in the log file. I think this means that it is taking the loads (convections, constrained temperature, etc) and applying it to the model. For some reason, it may not be recognizing that the load is applied to a suppressed part. If this is the case, you can suppress the loads that are applied to the suppressed part.

That is what I did, I un-suppressed the part and removed the part applied temperature.  It is running now. 

 

Thanks,
