Hi, everyone

I run a big soil model using OpenSeesSP, getting a error message:

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

=====================================================================================
= BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
= EXIT CODE: 6
= CLEANING UP REMAINING PROCESSES
= YOU CAN IGNORE THE BELOW CLEANUP MESSAGES
=====================================================================================
APPLICATION TERMINATED WITH THE EXIT STRING: Aborted (signal 6)

How to solve it ?

Thanks in advance!

any more info? can you build the model and this fails when the analyze command is issued?

Hi,fmk
The problem have been solved. I used -genBandArpack (default) as solver of eigen analysis. In fact with the model becoming bigger, genBandArpack was not available. Now I use SuperLU, the computing can be run. Which solver is the best using OpenSeesSP? Sometimes Mumps is not available.
Thank you for your reply!

Best wishes!

mumps is the fastest, but only works for parallel. though you can run them as sequential applications by using n=1 with mpiexec or just starting them as you would OpenSees (at least that works on my machine, not sure if mpi needs to be installed first)
