PARAM,WTMASS 1

[minny]

hi
in a buckling analysis (sol 105)
the model is in the following unit: inch, lbf (consistent).
Could you confirm (or not) that is mandatory to define the material density?
Could you confirm (or not) that I have to insert the card: PARAM,WTMASS,0.00259 ?

thanks

unless you are using self weight as part of the loading then material density or the inverse of g (inverse of 386 in/s^2) are not necessary.
