MSPhysics 1.0.3 (16 October 2017)

I have some problem to better "past" this articulated structure to the landscape!
Convex Hull is used.

What is the process for this sort of thing ?

Density, other sort of hinge, Friction, ... ?

Hi, I suppose the geometry of squares and hinges is the limit. Try with univeral joint instead of hinges. Then the squares can become to diamonds.

pilou

It's not square cube, it's yet "diamond"!

but maybe i have forgotten forget to give these Diamonds "convex" !
change the diamond in convex state ...not better!

Universal joint gives more liberties but "fall down" not more to the ground!

here with normal hinge no problem

pilou

I put all "diamonds" as Convex Hull : not many better...

I put all as Universal joints not many more better...

Shape of the ground: Static Mesh (The hill has concave areas)
Material of blocks: Concrete (More weight for the deformation)
Stiffness of Hinges: 0.95 (The geometry is otherwise too stiff, because the connections allow little lateral twisting.)

Excellent! i will study your solution!
I was desesperated!

pilou

So my biggest error was the "Concave surface"!

Will be very good for create very quickly some "roof structures" !

pilou

Seems very low intensity of Stiffness faraway element!

In case of concave surface maybe other joints can oblige the element to rotate more...? (universal...)
(not yet tested)

Here 0.1 stiffness

Hello,
I am trying to model a buoyant house simulation- However am having problems keeping the buoyancy in one plane. This is what the pontoon posts are for in real life. If anyone could please help me simulate this that would be great- thank you

Hello I am looking to model buoyancy, is there a way to stop an object falling over only buoyancy straight up and down

cristyan

Hello philhumphrey ! I have uploaded your file with some modifications. You have to play with density on the house and the buoyant material. and look how joint connection tool works or better you have to play a little with MSPhysics to understand how it works.For this you can download some file on 3dwarehouse searching "MSPhysics".

A cool site for tuto about MS Physics!

It's been so long when started using Ms physics tool and I have learned so many things from developers but the thing is found on YouTube or over here , is flying an object like helicopter and air plane,
J have downloaded a model of an air plane, the plane can fly yeah, sketchyphysics is used in that model, the I want to ask is, how can do that in Ms physics?

Hi, I installed the new SketchUp 2019 (Trial) to test it and I have obtain one error message in Ruby Console:

Thanks for letting me know. I sort of intend to rewrite MSPhysics over simply recompiling the libraries, which should take a while.

Oxer

Thanks for the info.

Hi there,

Im trying to apply breaking forces's to scaffold components to simulate when it will fail under a set load.

It looks to be possible by setting a breaking force to the fixed joint. the problem im having is the numbers are not making sense, e.g. when i rest a mass of 4kg on a joint with breaking force of 1962N (equal to 200kg of force) it breaks.

Am i messing up the settings?

Mass info
