Catenary curve validation

[armantekinalp]

@Ali-7800 will include a new validation case for PyElastica, by comparing simulations with analytical solution.

Hello everyone

I wanted to know if I can work on this issue as I am starting to learn more about the pyElastica package and would love to be able to contribute!

Hi @erfanhamdi

Thank you for your interest. You can go ahead and start implementing this case and create a PR when you are done together with simulation analytical comparison plots.

[armantekinalp]

@erfanhamdi Are you still interested in this issue?

[erfanhamdi]

I have simulated the catenary beam case and also the catenary chain but the problem is with the validation. I am not sure what should I use for it as there is an elastic catenary concept which seems to be closer to the catenary using one beam and there is this classical catenary which is defined for chains and ropes.
do you have any idea on that?

[Ali-7800]

@erfanhamdi You could try validating the catenary beam with the elastic catenary first, and then you do the rope which is unstretchable. We will give you more details on how to do an unstretchable rod afterwards.

@erfanhamdi how is this issue going? Do you have any questions?

Hello, I have some questions to ask. When the catenary is modeled, is the initial configuration of your curve a random straight rod, and then the catenary configuration that appears through iteration

[armantekinalp]

You can start with a straight rod. As the simulation progress rod approaches to catenary shape.

Example added, closing issue now.
