    Bolted joint in NX 8.5

    Hi, I have got a bolted joint in NX 8.5. I have applied only the bolt preload and kept the friction coefficient as 0. See attached gif image file, the bolts deform to enormoud magnitude without friction. I did not expect so. I expected wthout friction effect there might just be tenmsile...

    Pressure load in NX: A fundamental question

    I have just been reading the tutorial (as well as practising doing it) concerning pressure loads in NX. Now, if you recall the definition of pressure (http://wiki.answers.com/Q/Why_pressure_is_scalar_quantity_where_as_force_is_vector_quantity) we see pressure is a scalar. This is clear...
