How to draw bolt pretension in HyperGraph

As an alternate option, please request OLOAD output (along with NLOUT), then you can plot the applied forces (pretension force at the SPOINT node) from h3d file.

@Rahul R Thanks for your reply!
Because it doesn't show notice so I reply lately, Sorry.
Here I have choose my node at HyperGraph 2D.And I have set the OLOAD at my fem file.
But when I plot in HyperGraph 2D, it doesn't show my applied pretension force at the plot.
<?xml version="1.0" encoding="UTF-8"?>
Here I upload my fem file.

@Rahul R Thanks to your apply!
I have the same picture like you. And I use the same SPOINT with you.
<?xml version="1.0" encoding="UTF-8"?>
here I can get the SPONT ID from my pret file and out file it also the same.
Really thanks to you.

@Rahul R Sorry I have another question about if today I want to output the force of a surface.
Not the pretension.
How can I do at the H3D file in HyperGraph
How Can I do? Like this photo

If you want to get reaction forces using OptiStruct, then please add SPCF anf GPFORCE cards from Analysis page>> Control cards>> Global output request.

@Rahul R Thanks to your reply!
I have set the SPCF and GPFORCE like this
<?xml version="1.0" encoding="UTF-8"?>
At here I can't find GPFORCE format for h3d, but when I see help it can set in h3d
<?xml version="1.0" encoding="UTF-8"?>
And If I choose nodes to output the values it looks strange
<?xml version="1.0" encoding="UTF-8"?>
Here I have my h3d.file and fem.file.

To get the forces (for specific nodes) , can you try using the FBD tool in HV. You would need to have an op2 result file to visualize the same. You could even punch out the forces as a csv file.
I am attaching the relevant document FYR.

@Rahul R Thanks to your apply!
I have set to op2 for GPFORCE
But when I choose Results>Plot>FBD. At here I input the op2 file.
it will show

@Rahul R Thanks to your reply.
I have opened the HyperGraph2D successfully
At here I can't select the sum points of circle, I just can choose one node.
<?xml version="1.0" encoding="UTF-8"?>
Can I do that?
And when I choose Apply in FBD plot it can't plot.

Please follow the below steps.
<?xml version="1.0" encoding="UTF-8"?>
With the Pick: Elements selector active, pick the elements on which you want to plot. (for example as shown in the above image). Then, add those elements to FBD section (Click +).
Assign the system to it. then pick a node where you want the forces to be plot. Then, click apply.
Select the load case and then, you will be able to see the FBD plots. Also, you can see the values when you click on the highlighted icon.
Thank you

@Premanand Suryavanshi Thanks to your reply!
Because I have tried that I can output the pretension force.
And it can output but I can't draw it pretension with time curve.
Do you know where is my wrong?
I can export my node total force and it is the same.
I now have the problem because my op2 result just to show the last step result.
It doesn't have process so how do I show the time to pretension curve.
Really thanks to you.

Hi
Sorry for late reply. I was on vacation.
The applied force or the pre-tension force has to be incremental in order to plot the curve. I your case it is showing only the final load/result
Thank you
