Injection & Pressure Optimization

While Running Injection & Pressure Optimization Analysis , I get following error messages.  I will appreciate someone can help to resolve the issue

Hi, Mukund

It is sometimes happend with optim and runner balance analyses. Both analyses start a significant number of flow simulations, then read result files back to get the optimum. Theoretically they should attept to read result files after the job manager reported that the simulation results are written to disk. Unfortunately due to some glitches ( Windows' or Job Manager's) the optimization routine gets the signal that the simulation results are written when they actually are still in writing. The optimizer cannot get the simulation results and stops. Usually those errors disappear if the optimization is relaunched.

A few measures that help with those problems:

• Ensure there are plenty of free disk space for your project directory and temporal file directory
• Ensure that all the disk drives are defragmented and free of bad sectors
• Try not to overload your computer, don't run many analyses in parallel with you optimization problems
• Solid state drives are not very expensive nowdays, consider buying one for your system and putting the temporay files for your analyses there

Thanks for quick reply. My Comments for suggestion are

     There are plenty of free disk space for your project directory and temporal file directory yes, 350 GB

• Ensure that all the disk drives are defragmented and free of bad sectors  Yes
• Try not to overload your computer, don't run many analyses in parallel with you optimization problems Only optimization is running
• Solid state drives are not very expensive nowdays, consider buying one for your system and putting the temporay files for your analyses there Hard Drive is 10,000 RPM
• Re running analysis no luck.
