Hello, 

I have a problem with my last step in ANSYS - Solution (Solve). Geometry, Mesh is fine, but I still getting error: 
   

Text: "An unknown error occurred during solution.  Check the Solver Output on the Solution Information object for possible causes."

Association: "Project>Model>Static Structural>Solution"

I already tried everything.. 

Help me please.

You put the Pre-Meshed Crack coordinate system in the wrong place and it is pointing in the wrong direction.

Put the origin of the Pre-Meshed Crack at the center of the two faces of the crack.  Make the X axis point toward the crack tip, and the Y axis points in the direction of one of the crack faces.

You have a very coarse mesh that is inappropriate for Fracture calculations. The crack shown above is represented in the few elements at the center of the large thin-walled flat plate, between the two center ribs. 

Here is a more appropriate mesh.

I really appreciate your response sir , But I can't make the X-axis toward the tip

 Error Text: 

1-  " An error occurred when the post processor attempted to load a specific result. Please review all messages."

2-  " The result data for VCCT (G1) is not contained in the result file."

Warning text:

1- " You have requested a fracture result for a crack that is undefined: CINTG1"

2- " An iterative solver was used for this model.  However, a direct solver may enhance performance.  Consider specifying the use of a direct solver.  Refer to Troubleshooting in the Help System for more details."

3- " The fracture parameters computed during solution may be incorrect. Check the Solver Output on the Solution Information object for possible causes."

 

Help me please

How to make the same mesh setting like the last image you attached ??
