How to constraint one directon of Dof.

Keita

Hello @ all,

 

Is it possible to constrain one direction of Dof?

 

I want to prevent the object expansion,but not shrinking.

 

For example:

I want to enable the entire red line to move toword the object(Blue allow symbol) and to block a DoF in the direction of gleen allow symbol.

 

Is it possible and how to do this?

 

Thanks for your help.

Hello Keita,

In  a linear static analysis, you can use dependant conditionning using SUPORT entities, in particular using a cylindrical coordinate system for the cylindrical shapes.
Please take a look at document KB0113639 from knowledge base for details.

In a non-linear analysis, you can do this by modelling the environment as rigid walls (mesh+RBODY), then generating contacts between your part and this environment.
