Requesting Force output in MSC Nastran SOL101

dheeraj.kothapalli
I have applied pressure though a cavity. I need to output Element forces so that I can capture X,Y & Z force components on the surface where I have applied pressure. I went through Nastran documentation but I am not sure what should I request output for something like this.

    If you are just looking for the resulting forces at the nodes due to the applied pressure (not the actual element forces as a result of the analysis), you can request OLOAD=ALL in the case control (in Patran, this would be asking for the Applied Loads). This will print the resulting loads at the nodes in the f06 and also provide the results in the post-processing file (op2, xdb, hdf5) for use in Patran.
     
    Another option for seeing how each elements force is 'see' by the node is to request GPFORCE=ALL data recovery. This will provide the forces from ALL sources at each node in the model. The sum for each node will be zero, since the structure is in equilibrium, but it can be useful information for seeing the 'load path'.
     
    Let us know if any of these options end up working for you, and if not what additional information you need.
