Hi SolidWorks Users

I have a transient thermal simulation problem when using a temperature dependent cooling curve & was interested to see if anyone has had the same problem or if someone can suggest how to over come the problem.

In my transient study, I have applied temperature dependent materials to all parts (the study is of an assembly) & have applied various heat power & heat flux loads to these parts.  I have also set the initial temperature of all the parts to 300K & set the total study time to 28,800 secs (8 hours) with the set to time increment at 14,400 secs.  All parts in the assembly meshes fine, but when I run the study, I get the following error message:

I have since tried a few other total study times & found that it will run at 21,600 secs (6 hours), but anything longer than this, I get the same error message.  The range on the cooling curve I use is 410W @ 300K to W @ K.  The study does not run to conclusion as I know the temperature the coldest item is approx 20K & I know it would take probably 36-48 hours to reach this temperature.  I have triple checked all my materials data & heat loads & they are all fine.  I was using SW2011 & have now upgraded to SW2013 SP3 & the problem still exists.

Has anyone experienced the same problem or can anyone suggest what the problem might be?

Thanks in advance.
