How to retrieve ASET mode shapes (phi matrix) in HDF5 output?

Using the NASTRAN HDF5 = 0 command with DISP(PLOT)=ALL it appears that the mode shapes are for the G SET. In HDF Compass I see /NASTRAN/RESULT/NODAL/EIGENVECTOR has the same grid ID's from a USETPRT of the G SET. The A SET has 529 dofs while the G SET has 924.

Hi Matthew,

Nastran will always give you output for all the grids. Most simple way to control it is by having ASET grids specified via a set in the output request. In the example below 100, thru,110 are ASET grids. You will get the output for all 6 dofs of the ASET grids.

DISP=10

SET 10= 100,thru,110

Thanks,

Sanjay.
