Dear sir,
I am trying to execute the existing problem given in examples on OpenSees site. Ex5.
I am getting the following error. Please help me regarding this. Is there any issue with the installation of OpenSees.
OpenSees 2.2.1 version is installed on linux platform. Some basic examples I am able to solve w/o any issues.
BandArpackSolver::Error with _saupd info = -1
N must be positive.
Warning FrequencyAlgo::solveCurrentStep() - the EigenSOE failed in solve().
EigenAnalysis::analyze() - algorithm failed

Re: eigen value error
Can you tell me exactly what files are you trying to run from Example 5? I will try to do the same in order to see what is going on.

Re: eigen value error
When I ran this example I did not see the same error. The error I saw was related to inability of opensees to open ground motion file.
Try making the following changes and it should work for you as well:
1. Create the folder with a name GMfiles which is to be in the same folder with all the other files from this example. Unzip the ground motion file and copy H-E12140.AT2 to the GMfiles folder.
2. Inside of your element file replace the line:
set GMdir "../GMfiles/";
with
set GMdir "GMfiles/";
This is working for me so it should work for you as well.
