How to bond two surfaces of two solids together?
Does PATRAN/NASTRAN have the capability to bond two surfaces of two solids together? I tried to model an assembly consisting of two parts. The two parts share one surface. How can I glue these two together in order to obtain same nodes and mesh at the bonded surface? -
How to write the statement for MAX and MIN safety margin?
How to write NASTRAN statement for output of safety margin: MAXMIN (DEF) TTTT (BEAM,10) MAXALG(10) MINALG(10)? I know the how to write the ourput for stress and forces but don't know which word in NASTRAN is used for safety margin (replacing TTTT in the above statement). I tried to find it in... -
