Your hard disk drive ran out of free space while the solution was running.  Full disk. The corrective action is to delete half the contents of your disk and try to solve again. A better long term solution is to install a second HDD that is over 1 TB in size.

You can also reduce the amount of data written to to disk. Under Analysis Settings, Output Control, turn off Strain output. That will cut the data in half. You can also tell it to write data at intervals instead of for every increment of time.
