  Hello I want to generate the mass matrix in user format for the structure shown in the picture
  I used ANSYS Substructuring as follows
  /solu
  antype,substr
  seopt,file,2,1,0,RESOLVE
  LUMPM,1
  m,all,all
  /output,filename
  solve
  /output
  FINISH
  ! Mass
  *DMAT,MatMD1,D,IMPORT,sub,file.sub,MASS
  *PRINT,MatMD1,Mdense1.matrix
  
  But the computer goes out of memory although I use a high speed computer with 512 GB ram and 256 core processor.

  Hello,
  Can you try using the option to run solver incore?
  
  DSOPTION,,INCORE
  
  5.2. Types of Solvers (ansys.com)
