Hello,

In ANSYS Workbench, how the sum of Nodal Forces could be determined, in Report Review and Solve.Out Files, the Forces on each node are listed.

Is there a way to find Force Sum of all the Forces applied on multiple Nodes?

 Below is the listing of Nodal Forces from Report Review,

Hi Najeeb,

In the analysis settings keep the Nodal Forces and General Miscellaneous entries “Yes” to capture them.

In the Solution, insert a probe for Force Reaction. You can select the desired face using Geometry or Named selection feature. It is illustrated below. 

You can find more about the nodal forces here /forum/forums/topic/nodal-force/

Best wishes,

Hello Avnish,

For the "User Defined Results" for FSUM, the values are not the ones for the sum of applied load, but the "Force Reaction Probe for the Boundary Condition does match.

What is benefit of  Output Controls of Yes, for "Nodal Forces"?

The NX Pre/Psot has a tool for "Mechanical Load Summary" as shown below.  It gives the Total Load Applied. I am looking for the same way to find out the total forces (Nodal) in ANSYS Workbench.

Hi Najeeb,

You are right that when we use FSUM for a user defined result, it does not match the external applied loading. And probing the reaction force as discussed in the thread does give the total force on the selected face.

We need to keep Nodal Forces option in the Output Controls to "Yes" so that the solver can write the nodal forces in the result file.

And for your NX related query, I believe you may have to utilize command objects in the post processing to extract the required entities.

Maybe I request volunteers with expertise in MAPDL scripting to suggest the possible solutions.

 

Thanks & Regards,
