Unable to export mass and stiffness matrices on ANSYS 2022 R2

  Hi,
  I am unable to extract the mass and stiffness matrices of my model on ANSYS 2022 R2 with the basic apdl commands
  
  *SMAT,MatKS,D,IMPORT,FULL,file.full,STIFF
  *PRINT,MatKS,Ksparse.txt
  
  even though I have done this in the past on a different ANSYS version and I have seen someone achieve this with the 2022 R2 version. I see the following lines in the solution output
  
  EXPAND ALL EXTRACTED MODES
  DO NOT CALCULATE ELEMENT RESULTS
  
  DO NOT COMBINE ELEMENT SAVE DATA FILES (.esav) AFTER DISTRIBUTED PARALLEL SOLUTION
  
  DO NOT COMBINE ELEMENT MATRIX FILES (.emat) AFTER DISTRIBUTED PARALLEL SOLUTION
  
  DO NOT COMBINE ASSEMBLED MATRIX FILES (.full) AFTER DISTRIBUTED PARALLEL SOLUTION
  
  I wonder if it has anything to do with my my settings and configuration. I would really appreciate some help.

  Hi,
  Can you please check the DMPOPTION command? The DMPOPTION command controls how solution files are written during a distributed memory parallel (Distributed ANSYS) solution. This command is most useful for controlling how results files (.RST,.RTH, etc.) are written.
