have you created a set from these nodes you want to look at?
or you create a 'path' under 'tools' where you select the wanted points and plot the path with the 'xy' function where you must select 'path' as a source.
I hope this anwers you question.
Please follow the following steps:
1. Right click on XYdata from odb output or result tree. Select Create.
2. From the Create XY Data select ODB Field output.
3. Under Variables tab, under Position, select Unique Nodal. Then select CF1 or CF2 from CF: Point Loads and U: Spatial displacement to select U1 or U2.There are many more options there. You may select anyone you need. reaction, moments, displacements. etc.
4. Click the Element/Nodes Tab. Click Edit Selection. This will allow you to select any node from your model. Select the point of your interest.
5. Click Save. This will save your force and displacement data in separate files wrt time. Then close XY from Field output tab
6. Double click the XYData again. Click Operate on XY Data. There lots of option you can do. To simply plot the load displacement curve, you need to use the command combine(X,Y). Here X and Y are the displacement and load data file shown just below the command window.
7. Then click Plot Expression to do the plot. You can save the data for later also.
Pls let me know if this solved your problem or we need to discuss further.
Thanks
Initially you must create a set or path in the zone where you want to plot the curve (Tools>Set>Create), Then before submitting your job, you should specify the outputs which you want to plot, that here for your demand in the History Output, they're U1 or/and U2 or/and U3 (displacement) and NFORCE1 or/and NFORCE2 or/and NFORCE3 (nodal forces) based on the direction you want to know these outputs and specify the created set in the Domain section.
After completion of the job export and save the specific Displacement and Force and save them, they're based on the time (X axis), by using Operate On XY Data you can combine and extract the Load-Displacement curve.
Good luck with your research.
