I'm having a bit of difficulty making a temperature load constant. When I use the default settings, the analysis runs no problem. The temperature load seems to be applied linearly throughought the study. When I choose "use time curve" -> "user defined" and attempt to make the temperature constant throughout the study the analysis fails (error message in attached image). It almost seems like a bug in the program, but I'm sure it's just something silly I'm missing - the model is extremely simple.
The attached images hopefully illustrate my problem. The first is the constant temperature load I'm attempting to apply and the second is the failure message I get. I've also included a copy of my model (the first study works, the second does not).
The reason I'm using a NL analysis is because I want to later combine the temperature loading with a buckling study - right now I'm just trying to make sure my model behaves the way I want it to.
Thanks in advance,
