A fatal error has been detected during input processing:
  
  *** ERROR # 7007 ***
  The run failed because automatic memory expansion has failed.
  Currently allocated working storage is       8802 MB.
  Automatic expansion failed to expand to     22933 MB.
  The failed amount is the minimum required memory to complete the run.
  Please verify whether the system has enough memory and rerun the problem.

 

 

 Note that estimated disk requirement exceeded available space.
 See WARNING 1971 in the output file.
  

 

but i have 174 GB free, I am doing FRF. I have reduced stress range. But still no change in estimated disk size

    Hello,

     

    I am facing this error, Please suggest me a solution.

     

     *** WARNING # 1971
     Current run is likely to fail due to insufficient disk space.
     Estimated disk space requirement = 218377 MB
     Estimated disk space available = 171983 MB
      Suggestions to reduce disk space requirements:
     For static analysis - reduce the number of loadcases.
     For eigenvalue/buckling analysis - reduce frequency range in
     EIGRL card or number of modes requested.
     For FRF analysis - reduce the number of loading frequencies.
     For transient analysis - reduce the number of output time steps.

     *** ERROR # 7004 ***
     Not enough working storage for numerical factorization
     The run failed because automatic memory expansion has failed.
     Please see the previous error message for more information.
      
     This error occurs in module 'prpdrv'.
