Error in Example Problem

Post by hyunee »

Hello,

I got an error message and an warning message when I run one of the example problems in this site with OpenSees ver. 2.4.3. I did not get any error or warning message when I run the same example problem with OpenSees ver. 2.3.2. I did not make any change in the script and ran with exactly the same scripts for both versions. Actually, I posted the same question a few weeks ago for ver. 2.4.2. I have no idea that this is only for my case or any one met the same question. The example problem is " MRF_2Story_Concentrated".

Thank you.

Sorry for my late response.
I got two WARNING messages for the static analysis for gravity loads.
The first one is "Warning BandGenLinLapackSolver:: solve<>-LAPACK routine returned 4
The second one is "Warning NewtonRaphson:: solveCurrentStep<>- the LinearSysOfEqn failed in solve<>StaticAnalysis:: analyze<>-the Algorithm failed at iteration: 0 with domain at load factor 0.05
OpenSees>analyze failed, returned: -3 error flag

Even though I got an error message, I could get the dynamic analysis result and the it was right.

Thank you.
