i try to simulate simple thing. the box get dispaclement to y direction 5mm.

but i get an invald y component error so i cannot simulate this one. i use aluminum alloy material for geometry

i think it is related with solve process setting.

Hi

 

See the modal courses we have. One thing is that we can not have non-zero displacement boundary condition.

All the best

and what it means that we cannot have non-zero displacement boundray condtion. i set 10mm which is non zero

Hi

 

Sure:

/courses/index.php/courses/modal-analysis-in-ansys-mechanical/

/courses/index.php/courses/modal-analysis/

 

See also the help manual (seaech for modal analysis) where we specify this:

'All structural supports can be applied except a non-zero Displacement, a Remote Displacement, and the Velocity support.'

All the best

Did you ever figure this out?
