Explicit Dynamics error Post processor attempt

    • aamiralaracu1


      I am trying to solve an crash test or drop test in Explicit Dynamics. I have imported my model in an iges file and also made sure it is a solid. I created a wall in Design Modeler using the rectangle tool and then extruding it. once completed I meshed the model using the default mesh size. The mesh came out fine. I then made sure that the material properties were updated properly. for the drop component I used structural steel and for the test component I used aluminium alloy. i entered the initial condition on velocity as 50 m/s and forthe drop test the height as 30 m. in analysis setting i changed the end time to 0.00001.

      when I try to solve the simulation it comes up with the error (An error occurred when the post processor attempted to load a specific result. Please review all messages.) it also comes up with two warning messages (Current result file may not contain requested result data . Please clear the solution and solve again.) and (The result file  cannot be opened.).

      Can anyone help me in figuring what is going wrong.




      P.S. I have also attached the solution information if it helps. Please find below this message.
