Good day everybody,
I'm testing out the trial version of Simulation Muliphysics and I have a question about partioning and applying surface loads. I am relatively new to the Autodesk environment so this might be a very basic question. I am coming from an Abaqus and ANSYS background.
Can I not partition an exisiting surface to add a surface load to a specific area of the part? Please see the attached figure. The inside of the hole is defined by surface 1 and surface 2. I'd like to imitate a pin (as a surface pressure) acting on the the hole within the yellow lines. However, I cannot select that region without selecting the entire inside surface of the hole. I'm assuming that there is an easy way to do this but I haven't come across anything yet in this forum.
Any help would be appreciated.

Hi MB,
Out of curiosity, how would you do it in the other products you mentioned?
In Simulation 2013, one option would be "Setup > Loads > Bearing". You can apply this load to the "entire" surface of the hole, but the software knows to only apply the parabolic-like load to the portion that is plus or minus 90 degrees to the radial direction that you specify.
The second option would be to split the surface of the hole in your CAD software. If you want the load over a very specific area, this is the best method.
With the third option, you have limited control over the area. Simulation is a line-based modeler (compared to other codes that generate elements directly), so what you do is select the lines and change the surface number of those lines. Specifically
Hi John,
If I'm using your method 3 that you outlined in the previous message, do I need to select all the lines of all the element faces inside the region that I want to apply the load, or can I just select the lines that create a bounding box? Meaning that if I apply a surface load to a surface defined by a bounding box, will the software automatically apply the surface load to all of the element faces comprising that surface within the bounding box?
Thanks,
Todd
The short answer is that you need to select all of the line.
The technicalities are as follows:
