How to determine how many DOF a FE model has?
How to determine how many DOF a FE model has?
(OP)
Often you will see in articles the author stating that a FE model has xxx DOF to indicate how long it may take to run or to convey approximately how big the model is.
Could someone explain how I can get the number of DOF from either Patran or from Nastran output files?
Thanks :)

where n is a node, and d is the number of degrees of freedom at the node.
dof at a node can be fixed by the code (NASTRAN applied 6 dof at every node, those that aren't used are autospc'd)
or the code can assign dof depending on the element (a rod or a solid would have 3, a plate would have 6, a spring would have 1).
run statistics should tell you for a specific model.

For example in the command prompt.
"estimate.exe model.bdf"
