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)
