I am trying to do an static analysis on a car frame. Here I took a screen shot of a test run I tried in mechanica. It consists of two tubes meeting at about 70 degrees. You can see the red blob of polynomials about 3/4 of the one up one of the tubes. I recieve an error:
"The model is insufficiently constrained for the analysis. Please review the element connections,
properties, and constraints in highlighted entities. If this is a modal analysis, then you may be
able to obtain a solution by requesting additional modes."
If anyone could tell me where to go from here that would be great. Thanks.
