This is what I am getting (as shown below). Then, I am opening the MatKMMF.text file. I am using the * dmat command to create the dense stiffness matrix. After applying the Boundary Condition, the stiffness matrix from MATLAB is as follows: Hence, the stiffness matrix will be a ( 2x2) matrix. However, my APDL code generates the MatK (name of the stiffness matrix) file properly. Is this error a concern not to provide the stiffness matrix properly? Could you please let me know? Yes, there is NO "file0.full" file in the Directory (or Folder)". However, I am getting an error message when I am executing the command " combine, full!! combines all file*.full into file.full". Then, I executed my APDL code line by line. I defined the " Directory (or Folder)" where all the files could be generated or saved. This is what I did to get the stiffness matrix.įirst, I open ANSYS Product Launcher. !! Before making elements, we must recall ID #Į,1,2 !! e - making elements by node by nodeĪny suggestions will be highly appreciated. !! Make FE Model, make nodes and elements !! Extracting Stiffness Matrix from ANSYS APDLįinish !! It will finish all previous work How could I let APDL know that I am interested to get the stiffness matrix as an output? Could you please have a look my APDL code as listed below? Rather, I want APDL to provide me the stiffness matrix? Is it possible? Is it possible that ANSYS APDL can create (or provide) the stiffness matrix? I am not asking to import the existing stiffness matrix.
