hello, does nastran 2012 segment to segment contact cannot includ friction? may i have any alternative. or i must change my model

Hello, I wont to model the shaker vibration using sine wave using msc nastran. this shaker is monted at the climped end so i constraint the 1..3.4.5.6 dof and i apply a sinusoidal force at this climped end. the shape i found are wrong. may some help me

Hi, how can i using freqyency response analysis retreive the modal damping value? thx

Hello, Can'I using a modal analysis determine the effect of friction on the modal damping value of a structure? or I must apply a sinusoidal force and guettig the the damping value correspending to the modal frequency. thx

hello, Can i determine the effect of friction on the modal damping values? using a finite element method

hi, i need to simulate a sample excited with a shaker. i must imput a sunusoidal displacement at the clamped end of the sample and the i recover the response from the free end . i use the dirct frequency response analysis. i ask if some one can help me to imput the sinusoidal displacement.

Can I add contact with friction in normal modes analysis sol(103) using Msc Nastran? If not is there any other alternative? thinks

hi, I start to work with msc Patran/nastran. i have problem with the servor: when i run the analyse nastran don't generate the .Xdb file it generate only the .f04 and .f06 files . and in the .f06 file it mention 'fatal error 3060'.
