About analysis errors
Two types of errors can occur during calculation: fatal and non-fatal. RAM Concept generates an Analysis Error message if an error occurs.
If a fatal error occurs, analysis cannot continue. You must correct the problem, then recalculate. For example, if the structure is unstable then RAM Concept cannot triangularize the stiffness matrix.
After non-fatal error occurs, you can choose whether to continue the analysis calculation or not. For example, if a point load is not located on the structure, you can do one of the following:
