Reading large .sto files

[William A]

Dear All,

I am facing problem in reading large .sto files using STOFileAdapter(). Although it works for reading small files. Can anyone suggest on how to read large .sto files. By large I mean 100s of MB.

Thanks,
William

That sure is a big file

The adapters were not tested on files that large, so the expected behavior is undefined. At this point in time, I would say that is unreasonable to expect the adapters to handle files that large. Could you give us more details on your use-case? How was the STO file generated/Why is it necessary for the STO file to be that large?

I am using forward dynamics tool and I have defined controls for large duration say 500s. At the end of the simulation, the states are stored in a .sto file which is large (since integration is till 500s). Now, I want to read that file. Any suggestion?

Are you getting an exception reported, or is the performance poor?

[William A]

No, I am not getting any exception. It is just not finishing reading up the file (waited for hours and hours).

There is little that we currently do, other than recommend that you break up the file into smaller chunks or run smaller simulations. I have filed an issue so it may be investigated in a future development sprint.
