I have made the modification. The updated tool is available for download from the tool website: https://simcenter.designsafe-ci.org/research-tools/ee-uq-application/

you can check it out at new online doc:https://nheri-simcenter.github.io/EE-UQ-Documentation/common/user_manual/usage/desktop/FEM.html

I have updated the tool to include OpenSeesPy. The updated tool can be downloaded from the website. Thanks for posting this. A number of users it seems wanted OpenSeesPY!

the 2 files you mention are created by OpenSees when it runs the Ex1b.Portal2D.EQ.tcl script. The following are the two line in the script that generate these files:

recorder EnvelopeNode -file PFA.out -timeSeries 1 -node 3 -dof 1 accel;         # Peak Floor Absolute Acceleration
recorder EnvelopeDrift -file PID.out -iNode 1 -jNode 3 -dof 1 -perpDirn 2

it is the python script  PortalFrameSampling.py that causes OpenSees to run multip[le times to perform the sampling. If you look you will see that for each invocation of OpenSees, the python script creates a directory, runs OpenSees in that directory, reads the results in the 2 files you are looking for from that directory, and then DELETES the directory. If you want to see the files after the python script is run you will need to comment out the line removing the directory (line 40):
           
          shutil.rmtree(sampleName)

note: depending on your version of python you may need to change the prints at the bottom of the. said python script to something like:

#Printing results                                                                                                                                         
print ('Mean Peak Floor Acceleration: ', np.mean(PFA))
print ('Peak Floor Acceleration Std. Dev: ', np.std(PFA))

print ('Mean Peak Drift: ', np.mean(PID))
print ('Peak Drift Std. Dev.: ', np.std(PID))

I contacted Prof. Lu. It is based on regression. The relevant info is shown in the attached image which is a screen shot of what he sent.

The details of the calculation of lambda can be found in Appendix A of Lu X , Han B , Hori M , et al. A coarse-grained parallel approach for seismic damage simulations of urban areas based on refined models and GPU/CPU cooperative computing[J]. Advances in Engineering Software, 2014, 70:90-103.

 

started working on the source code changes necessary to implement the feature

Just to let you know that i have started code development. When done, i plan to make available to you to test the new feature.
