Another way is to partition the volume into two volumes so that there is a boundary where you want to apply the load.

I got your concept. Actually if the assembly is complex and have to define load point by coordinates (x,y,z) axis,,,,then it will be much simpler.

Whether MATC can define point nodal coordinates.

Dear Friend,

I am new to drawing packages, I want your guidance, how you Partision Image by which Software package.

Kindly guide.

I use Salome, very powerful modeler and mesher.

It exports mesh to unv file and ElmerGrid will translate

Dear Friend,

I have checked Target Coordinate Command by Physical Calculation.

The Load shows Equally Distributed and not Point load or line load at target Coordinate.
I have check for both linear and non linear, displacement is same.
Kindly check below and correct myself.

Try with

Boundary Condition 2
Name = "load"
Target Coordinates(1,3) = 500.0 0.0 50.0
Displacement 2 Load = 1.0e+07
End

ELMER Team Must make this Problem Simple.

Load at Exact Point in terms of Coordinates (x,y,z) Must be Able to Define by define by Mouse... Arrow Mark.

End

Displacement 3 = 0
Displacement 2 = 0
Displacement 1 = 0
End

refer paraview output same as above...MATC command not defining coordinates at exact distance,,,but defines predefine deformation on x and z axis..by 500mm and 50mm..
