FAQ
ParticipantThis error code 18 is a write error. This could occur due to permission issues, network communication problems at the time of the write, or even a virus scanner checking the file at the time of the solve. However, in the majority of cases, this error occurs due to disk space being full – either the total drive space or the allocated space within the user account folder (Scratch directory). Please make sure that you have adequate hard disk space available for the run. A rough guideline for required space can be found at the following link in the Ansys help: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v194/ans_per/perlineqsolv.html If one can confirm that there is enough disk space, first determine if the analysis will solve w/o error in Shared Memory Processing (SMP) mode (i.e., Uncheck Distributed Solution under Tools>Solve Process Settings>Distribute Solution). If this solves, then the user can also try Distributed Memory Processing (DMP) mode as well.
