More RAM allocated than physically installed

      Hello,


      1. how does Ansys translate MB's of RAM to GB's of RAM? (MB/1024=GB?)


      2. how can it be, that Ansys allocates more RAM than physically available? (and then fails to compute the solution with direct solver)


       


      Regards,

      Hello Marvin,


      The solver can fail to compute the solution for many reasons which have nothing to do with running out of RAM. Please provide more information.



      • How much RAM is installed in the computer?

      • Are you looking at Solution Output to see the RAM that was allocated? 

      • Please insert an image of a screenshot of the RAM allocation into your reply.

      • What is the error message in the Solution Output?


      One example of when ANSYS will allocate more RAM that is available, is on a computer with only 2 GB of RAM installed. The reason it does this is because the published minimum RAM specification for ANSYS is 4 GB, so some defaults in the program assume that is available. I have helped Students with only 2 GB of RAM to change the default so that small problems will solve on a 2 GB computer.


      I believe the correct conversion from MB to GB is 1000 MB = 1 GB.


      Regards,
      Peter
