I have a structure consisted of brick8N elements and I'm dealing with some problems...
1)Since I have defined the mass density (mass/volume) during the definition of the brick8N element, is it sufficient for the dynamic analysis?
2)Can I apply the gravity loads to these brick8N elements using the command "element surfaceLoad" with the pattern of "eleload"? And how about the self weight? Should I apply it manually, gradually increasing it to the bottom? Or is there any easier way? (my structure consists of 2500 brick8N elements...)
3)Are the axis x,y,z of these brick8N elements the same whether they belong to a "column" or a "beam"?
Thanks a lot!

Re: Brick elements-mass and loads
1) yes
2) yes you can use "element surfaceLoad" to apply gravity loads and selfweight. You can write a script to define this load.
3) the axis x,y, and z are global axis
