Sparse Matrix Solver and out of core memory mode.

[AM_10402502]

How can this error be resolved.

Delete unimportant files and make the free space in the drive (that your working directory is under it) at least 60GB.

It was a complex problem always failed my simulations. In the end I found out the root cause was such a simple one: there have to be enough free memory space in the workspace in order to run a simulation.

Yesterday I ran 16 simulations overnight, and failed one modal analysis. I found out in the morning that the free memory left in my drive is only 23GB. So I am to delete files or transfer them to outside depository.
