How to plot a range of values from a simulation
Hello, i am currently using Motion View to simulate a suspension geometry and I performed a Kinematics and compliance Analysis. But the standard analysis reports are not enough for my analysis.
For example I want to plot the displacement of the spring or shock vs wheel center displacement, but when I do so the entire date of the analysis is plotted and I get these values on this yellow area.
What I want to know is how to select certain part of the analysis to plot. For example only the part where the ride analysis is performed or the steering analysis is performed. Because the standard reports, only plot a certain range of data generated from the ptl file.
I am using the templates provided by Altair of Formula SAE suspension to build the models and perform the analysis.
I also want to know if there is a list that relate the requests and components that are generated from the user defined outputs, because I would like to know if the Roll center height is one of this variables. So I don´t have to create it.

Hi @Pedro Dias
You can trim the curve in HG if you know the timestep where the steering analysis starts for example.
For the list of outputs, you can get it from the model file under outputs.

I am not beeing able to trim by timestep, because the graph I am plotting is not a function of time. I am plotting for example a graph of wheel center displacement Z x shock displacement Z. When I select the trim option on the modify curve tab, it doesnt show me a option to trim by time, only by X and Y coordinates.

Hi,
You can try to use the 'subrange x' command from 'Plot Macro' icon.
In the attached example I have to resample the curve before, since the command need points inside the range of cutting.
I'm not sure if it is a core macro or coming from MVP Toolbar.
Anyway, if you manipulate curves in Hypergraph, installing of MVP Toolbar is highly recommended. (Altair Macro Toolbox for HV, unsupported but very powerful).
(For install help look into: https://forum.altairhyperworks.com/index.php?/topic/23212-average-multiple-curves/ )
If you want to cut the curves in time range, then you have to do it for both curves before plotting curve1.y vs curve2.y
Best Regards,
Mario
