Hello,

I am trying to extract the load vs displacement curve for a static analysis. I apply a pressure load on a surface (element based), in the vertical y-direction (direction 2). I also request a history output of CF2 and TF2. When I look at the output database, and extract the nodal output, I see zero force. Below are the keywords in my input file.

**************************************************

*DSLOAD

Cups-RB_Bottom_Surf, P, 2.81046

*OUTPUT, HISTORY

*NODE OUTPUT, NSET=Cups_Bottom_Surf

CF2, TF2

**************************************************

The node set belongs to the element-based surface mentioned above. As in, the nodes are a part of the elements that form the surface. 

When I extract the curve from history output for any node in the nodeset, I see zero force throughout the simulation time. Where as, when I extract displacement of that specific node, I see its value changing over time. 

When I look at the deformed shape animation, I see the object moving due to the applied force. So, the force is definitely being applied, I'm just not able to extract it.
