Force Vs Displacement Graph in Hyperview

NoorAlam_08

Hi Everyone.

Can anyone help me how can generate force vs displacement graph in hyperview.

I am doing a impact analysis in radioss but i am unable to generate the Reaction force vs Displacement graph.

Can anyone help me the process to generate force vs displacement graph.

Hi,

Kindly find the video link for your reference (demonstrate basic plotting in HV): https://www.youtube.com/watch?v=IdwBQ-YOIr8

Since you are performing analysis here, you can load the result file (h3d) in HV/HG and plot the graph.

Thank You

Hi.

I have generate Reaction Force vs Time And Displacement vs Time graph.

But i need from these graph to Reaction force vs Displacement graph.

Can anybody know how be find this graph.

Hi,

if you have a base of curves DISP-vs-TIME and FORCE-vs-TIME, and would like to do a crossplot to get e.g. FORCE-vs-DISP, then I recommend one macro / function from the MVP Toolbar (btw I need to check MVP support for Student Editions). One of those:

The function is defined in MVP as:

          function sync2y(c1x,c1y,c2x,c2y,flag)
            {
                min2c = max(cat(min(c1x),min(c2x)))
                max2c = min(cat(max(c1x),max(c2x)))
                ptsrangec1x = numpts(subrange(cat(c1x,min2c),min2c,max2c))
                ptsrangec2x = numpts(subrange(cat(c2x,min2c),min2c,max2c))
                if(ptsrangec1x >= ptsrangec2x)
                    newx = c1x[subrange(c1x,min2c,max2c)]
                else
                    newx = c2x[subrange(c2x,min2c,max2c)]
                endif
           if(flag == 1)
                newy = lininterp(c1x,c1y,newx)
           endif
           if(flag == 2)
                newy = lininterp(c2x,c2y,newx)
           endif
                return newy
            }

The Macros using this function creates a new curve with these vector definitions:

<?xml version="1.0" encoding="UTF-8"?>

This way, not matching vectors are sychronized, compared to using the definition
x=p1w2c1.y / y=p1w1c1.y
as new curve, where e.g. an Offset of original curves would not be recognized. So the way described above should be the clean way to do this.

Unfortunately I do not find a better documentation for this specific function. Hope this helps.

If you request the force and the displacement on the given node via /TH, you will be able to create the force vs displacement with HyperGraph.

Please refer to the Radioss documentation of the keyword /TH
