SolidWorks Simulation - Remote Load

[IdanPV]

Hello All,

I have a question regarding the use of "Remote Load" in SolidWorks Simulation.
Here is the problem:

I have a force (green arrow ) of 79kN acting on the solid red bar.
I don't want to model the red bar in my FEA, so I decided to use the "Remote Load" option.
I set my local coordinate system but now I have few questions:
1. Which type of load shoud I use - Direct transfer or Rigid connection?
2. What are the differnce between the two types?
3. To which face and\or edge in the model should I connect the load?

 

[FEA way]

Direct transfer type should be used when ignored component has similar stiffness to the one being modeled. The software simply applies equivalent forces to selected faces. Rigid connection means that rigid bars are used to transfer loads and thus the selected faces become rigid. As a result some spurious stresses may appear in the vicinity of these surfaces. Is the red bar stiffer than the rest of the model ? I think that it would be best to try both options and compare results.

The choice of surfaces for remote load depends on the way the red bar is connected with the rest of the structure. Is the bar tied to the model or just in contact with it ?

Hello FEA way,
Thank you for your help.

The red bar made from the same material as the rest of the model (all parts are made of stainless-steel).
The red bar is attached to the rest of the model by bolts.
