Hi Behnam and Hugo,

Thank you, both of your help is very appreciated!
I shall try this immediately!

Kind regards, Edd.

Hi @Hugo

Thank you I really appreciate it!

Did you have any luck regarding modelling the daisy chained springs previously mentioned?
Thank you for your help!

Kind regards, Edward

Hi Hugo,

I understand, as this was something I originally looked into. My issue is that one of the requirements of my models is that it must execute in real-time. I will be modelling from the femoral artery all the way up to the aortic arch,and have been told in a different thread that FEM would unlikely handle real-time execution with the additional load.
For this reason I am initially developing two analytical models (mass-spring & rigid multibody); then perhaps if I’m successful with that I may consider a hybrid model between FEM and analytical.

Thank you!

Hi Hugo,

Thanks for the response!

I am looking at making two models, first a series of rigid links connected by rotational joints, (figure 4 of this link https://www.spiedigitallibrary.org/journals/journal-of-medical-imaging/volume-5/issue-01/010902/Navigation-of-guidewires-and-catheters-in-the-body-during-intervention/10.1117/1.JMI.5.1.010902.full)
For this I have used articulated system mapping along with angular stiffness and feel that I have made progress.

My confusion is with the second model, it is very similar to the first model, however each joint has a linear spring between it also as shown here. https://www.researchgate.net/figure/Mass-spring-model-of-the-catheter_fig3_261735316
My problem with the articulated system mapping is that the articulation points for each rigid body appear to be fixed relative to one another.

Any advice on this would be greatly appreciated, as I have spent a fair while trying to make it work!
Thank you.

Hi Camille,

Thank you for the response, it is very helpful!
I have already spoken with Hugo about that plugin actually, thank you.

Kind regards, Edward.
