The normal force and tangential displacement imposed
condition combines displacement and force boundary conditions described in Normal and Tangential Displacement Imposed and Normal and Tangential Force Imposed, respectively.
The default condition corresponds to f
= 0 and d
= 0, but you can assign nonzero values for the normal force
f
. It is not possible to assign a nonzero value for the tangential
displacement d
due to orientation conventions in 3D.
To define the normal force and tangential displacement on a boundary section, you will need to do the following:
Select Normal force and tangential displacement imposed (fn, ds) from the list of boundary conditions.
Normal force and tangential displacement imposed (fn,
ds)
Specify f
as Constant or Linear
function of coordinates. Select the Upper level menu. Ansys Polydata will open the menu where you can specify d
as Constant, Linear
function of coordinates, Map from CSV (Excel)
file, or User-defined function (2D
only).
