Errors in 3D truss modelling or analysis

Hi to all. My goal is doing an IDA analysis on Domes (spatial/space one), but in modelling I faced errors in doing a simple linear static analysis. Errors like these: "WARNING BandGenLinLapackSolver::solve<> -LAPACK routine returned 8 WARNING NewtonRaphson::solveCurrentStep<> -the LinearSysOfEq...

Re: Can truss elements be used in 3D modeling?

Hi. I saw your answer to " jgeis " regarding to use truss elements in 3D models. You mentioned there that the number of constraints are low and maybe this cause the solver errors. I have a similar problem but my model is not unstable. My goal is doing an IDA analysis on Domes (spatial/spac...
