Femap Post-Processing

Femap Post-Processing

Femap Post-Processing

I have two questions, but first off I am running FEMAP v11.1.0 64-bit with NEi Nastran Solver. I am running a static linear analysis. Now, my first question is about post-processing in Femap

1) I am trying to determine which value of Von Mises stress to use in my report. I have two values, one is from clicking F5, and under "Contour Style", choosing the Criteria radio button, from what I have seen this shows elemental stresses; for example I am getting a value of 96 ksi in the area of interest. The other value is acquired by clicking the Contour radio button and then clicking F6 -> PostProcessing -> Contour/Criteria Style, and choosing Max Only . For this second value I tend to always get a higher value, example in my current model the stress is 142 ksi. Can someone help explain the difference? Thanks.

2) My model uses connections and I am uncertain of the connection properties to use. See figure for visualization - so for the side of the "buttons" I am using an unsymmetrical contact with MAXAD set as automatic, and the bottom of the "buttons" I am using a bi-directional slide connection property. Is this correct?



RE: Femap Post-Processing

1) There are several contours to plot ...
a) element centroidal, and it'll plot
i) continuous (the results are displayed with continuous variation from one element to the next) or
ii) discontinuous (each element has one value only)
b) nodal, and it'll plot
i) nodal maximum (the maximum value from any element at each node) or
ii) nodal average (obviously averaging the different values at a node).

2) I don't understand

another day in paradise, or is paradise one day closer ?
