Point Mass in Static Analysis

  Hi, regarding the point mass condition in static analysis, I'm experiencing a problem. Assigning a mass to a point with its mass moment of Inertia, I get no results from AIM. The displacement is zero and the stress is zero, as well. I attach a simple example. Do I miss something? I need to simulate a concentrated load collocated remotely from my geometry. What's the best strategy? Thanks and regards

  Hi MicaOli
  
  Can you please share the model again. There seems to be an issue with the attachment and I am unable to access it.
  
  Also, just to check, did you apply gravity in your model? In a static analysis, the added mass can only apply a load equivalent to its wight (M*g) if acceleration/gravity is also present in the analysis.
  
  Regards,

    Gaurav_ANSYS , Hi! No, I didn't apply gravity in the model. I tried right now and it works. That was the problem, probably. I suggest to indicate this procedure in the manual and eventually add a warning message when you apply a point mass condition.
    
    Thanks in advance and have a nice day
