      The most likely cause of this failure is that the results file is corrupt. If so, it won’t be possible to restart from this file unfortunately. Corrupt files are rare. The most likely reasons for a corrupt file are that the solver failed while it was writing the output file (for example if the system ran out of disk space or a power failure occurred), or if the file has been copied (for example via FTP) it may have been damaged in transfer. Try to recopy the file to see if the issue can be avoided.
