I am running into an issue while running a huge problem with elements and nodes as follows:

          NUMBER OF ELEMENTS IS                              29983200
          NUMBER OF NODES IS                                 30273673
          NUMBER OF NODES DEFINED BY THE USER                30273673
          TOTAL NUMBER OF VARIABLES IN THE MODEL             90821019
          (DEGREES OF FREEDOM PLUS MAX NO. OF ANY LAGRANGE MULTIPLIER
           VARIABLES. INCLUDE *PRINT,SOLVE=YES TO GET THE ACTUAL NUMBER.)

So the error I get is as:

***ERROR: Abaqus/Explicit has encountered an internal error during the
 ***ERROR: analysis. Please report the issue to local office.
7/27/2021 11:06:20 AM
Abaqus Error: Abaqus/Explicit Packager exited with an error - Please see the
status file for possible error messages if the file exists.
Abaqus/Analysis exited with errors

I tried Google search, this it says the issue is with memory limits. I have a 128 GB RAM computational power; shouldn't this suffice? Is there any way I can make full use of my RAM?

I have added this line:

memory="98 %"

in abaqus_v6.env file, but it didn't help.

Any help is appreciated.
