Flex Body Assign Problem

Altair Forum User

Hello All,

 

I have been trying to build a full model which flex bodies, contacts included but when I assigned a flex body to rigid body , contacts are no longer available. Is there any specific contact type that I have to use for flex bodies ? and the other question is my material will be rubber and I want to examine how those components assigned flex body distorted ? Can I examine that kind of solution via MotionView ?

 

Thanks in advance /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />

Hi Abdullabh-

 

To answer your second question, the math behind flexbodies is based off of linear deflection, and linear material properties.  You will not get good results attempting to model a rubber component as a flexbody.  If you need to model something like a rubber component, you should investigate using the non-linear finite element feature in MotionSolve (NLFE). 

 

For your first question:  MotionSolve does not currently support 3D contact with flexbodies today.   There is a workaround to this, where you attach many small rigid bodies to your flexible body with fixed joints.  These small rigid bodies can then be used with 3D contact.
