Hi @Ivan Any alternative to do such in 13 version
Here is a work around to apply acceleration load using GRAV card to only a part/component of the structure. Change the material density to zero where you don’t need acceleration load to be applied and retain material density to the parts/component where you want acceleration load to act.
Or you can manually apply acceleration forces (F=m*a) on each node, where m is mass of individual node.

Hi,
I did the first option, but as this being a buckling mode check analysis where mass will play important role. If I make density as zero, mass becomes zero
Hi @gopal_rathore
ACCEL, ACCEL1 and ACCEL2 cards enable acceleration loading at Specific GRID Points.
Unfortunately, this functionality is only supported since version 14
