I'm an aerospace engineering student from Italy, I'm preparing my thesis with ANSYS and I've got some problems: the objective is obtain the stiffness matrix of my composite plate, but ANSYS seems like to always reject my request with this error:
*SMA Command : Fails to open the file file.full.
That's the code I used:
! Gets Stiffness Matrix
*SMAT, MatK, D, import, full, file.full, stiff
*SMAT, Nod2Bcs, D, import, full, file.full,NOD2BCS
*print, MatK, matk.txt ! Exports Stiffness Matrix to Text File
*export, MatK, mmf, matkMMF.txt ! Exports Stiffness Matrix as MMF format
I'm also attaching my project if you want to know more about it. I use ANSYS 19.2.
