Problem with reaction forces in ABAQUS.

Problem with reaction forces in ABAQUS.

Problem with reaction forces in ABAQUS.

(OP)
Hi everybody!

I've got a problem in calculating the reaction forces in Abaqus.

I assigned a boundary condition (U1=0 U2=0 U3=0) to a cylindrical surface; a high number of nodes lies on this surface. I created a set (based on the geometry) that consist of this surface, to have the possibility of examine the results and plot them on a graph.
When I check the results, the program shows me the value of the reaction forces in every node that lie on the surface, but I'm not able to calculate the global force, resultant of all the forces that the constraint exerts on the surface.

How I can calculate the resultant?

(Because the surface is cylindrical, I can't use the "view cut" tool).

I attached a photo of the geometry of the system I'm studying.

Thanks! :)

Use *Node print, total=yes, nset= <CR> RF

Hey

I would suggest the history output feature.
In its domain field, hover down to Set and select the set whose resultant you want to see. Assign the type of results you want for that node.
After the Analysis is over, head to Result -> Field History Output.
In here, select the type of result of nodes whose resultant you want to observe. For example if I want to see RF1 for all the nodes, I'll select all the RF1 result out of the available results.
Finally, click on Save As and select Sum out of the options given.
It will plot a graph in which you can see the resultant of the force whose value you can find out through the XY data feature.

Hope this helps!

Thank you so much guys!

I used the solution proposed by WayneKagawa because it seemed to me simpler; in fact, I prefer to use the graphic user interface, rather than the "command line"

Bye! :)
