Why did OPENSEES crash when I exported the M K matrix?

Post by tyj » Sat Dec 07, 2019 5:58 am

Hello
When I use the printa command to export a matrix (full rank matrix) for a large model, OPENSEES exits directly. Is there any solution? Can OPENSEES export sparse matrix or other matrix forms?

Thank you

Did you make sure that it exists at the PrintA command, could there be something else that is wrong ?

Thank you for your answer.
This is my printA command :
system FullGeneral;
constraints Plain ;
numberer Plain;
test EnergyIncr 1.0e-10 200 5;
algorithm Newton
integrator LoadControl 0.0001
analysis Static
analyze 1
puts "success"
printA -file matrix.txt;
I did the seismic time history analysis of the model without any mistakes,but I used system is UmfPack command.In the process of running, there is a phenomenon: after using the fullgeneral command, the running memory of the computer increases rapidly, up to 99%, and the running memory of my computer is 16g. After a period of time, the OPENSEES flashback problem occurs. Is there any solution?
Thank you

Is there any simpler solution? The above solution is quite complicated for me. tiny fishing
