you have not removed the temp node, as i've suggested before.

So this node is flying in space, and you have constrained this node only.

So as the rest of your model is not properly constrained, your NL analysis does not converge.

 

clear the temp nodes, redo your boundary condition and then re-run the analysis.

Great , no error but the animation of beam seems like it changes its shape when bending!!!

Great , it is done , for a week force , the beam behaves as it is supposed . thank you so much adriano.you made my day .

for a force ( 2N) , it is peroperly done.

Dear , Mr adriano , you really walked me through a great method to simulate a follower force , and it will be the fifth chapter in my thesis ( you will be mentioned there)  , So , is there a way in hypermesh to calculate the ( x1 x2 x3 ...xn) when applying the force , see the picture bellow

assuming that you have your model running and you got the result, this would be just the global 'y' displacement component of your model, that you can easily contour in HyperView and then query.

Yep the model is properly working , How to query  !!!

in HyperView, plot the displacement in the desired direction, and then use 'Query', and click the desired nodes.

or you can use the 'measure' function, use 'node path' and pick your nodes of interest, and 'Create Curves' to plot them. (value x distance)

where can I find 'plot ' !!

the same video i've shared before for rigids shows how to create beam elements.

you should find something in Altair University or their youtube channel.

 

for your model, having only the disks geometry modelled into the CAD is enough, including the points for attaching the beams.

In HM you will create first the 2D mesh, using the fixed points as reference.

 

I'm attaching a very basic video as well, but again, go after some training material in Altair University.

 

 

Hello Mr adriano , How did you create the four nodes on each circle  !!!

these are originally 4 geometry points in each circle, so HM forcelly creates nodes on them.

 

I've created them as fixed points in the 'quick edit' panel.

selecting one line and adding a N points. Usually circles have only 1 point. You can add 3 more.

My  co-supervisor told me that , as long as you came across this software where you can model a follower force on our robot , then stick to it but the problem is in my univ no one has used hypermesh and none of the teachers heard about it , thus it is of a great interest . I will mention you in one of my chapters Mr adriano . thank you so much for your valuable help
