i tried to use next orders with ANSYS Workbench 2019.2 to export mass and stiffness matrices :
!Stiffness
*DMAT,MatKD,D,IMPORT,FULL,file.full,STIFF
*PRINT,MatKD,Kdense.matrix
!Mass
*DMAT,MatMD,D,IMPORT,FULL,file.full,MASS
*PRINT,MatMD,Mdense.matrix
The shown codes worked out with workbench R15
When i try it with Workbench 2019.2, i had next error
(*DMA Command : Fails to open the file file.full.)
some friends told me to use next code for sparse matrix
*SMAT,matk,D,IMPORT,file.full,FULL,STIFF
*PRINT,matk,matk,txt
i received an error :
( *SMA Command : The File Format (FILE.FULL) is not recognized. This command is ignored.)
do any one face such problem and how i can mange this error?
There is a particular stpl file in which mass and stiffness matrices are exported.
the problem is in the ansys virgin, it worked out with ansys 15 . Errors appear in virgin 2019
Hi Mostafa,
the following works for me in 2020R2.
/AUX2
! Combine .FULL files
COMBINE, FULL
! Enters the database processor
/POST1
! Stiffness
*DMAT, MatKD, D, IMPORT, FULL, file.full, STIFF
! Mass
*DMAT, MatMD, D, IMPORT, FULL, file.full, MASS
! Sparse matrices
*SMAT, MatKS, D, IMPORT, FULL, file.full, STIFF
*SMAT, MatMS, D, IMPORT, FULL, file.full, MASS
! Write matrices to files
*PRINT, MatMS, Msparse.matrix
*PRINT, MatKS, Ksparse.matrix
*PRINT, MatKD, Mfull.matrix
*PRINT, MatMD, Kfull.matrix
