Yesterday I was working with a couple models (Piers) with different loads applied on it. Everything was working properly; however, today, I modified some of loads. When I tried to run analysis, I get a message: "Frame Analysis Failed! Frame Model Unstable". I wonder what could cause the problem, and how to solve it. From my view of point, this failure is related to the software because I also tried to run analysis for one of the tutorial files, and I got the same message. If anybody knows how to solve it, I'd appreciate to share with me the solution.
