Variable dependant load in Ansys 2

[julia_page]

Hi,I want to know if there is any way in Ansys Mechanical to introduce a load that is calculated from a result of the previous time step. For example, a force depending on the deformation of each node.

Hi,
you have at least 2 options:
1/ the simplest is way would be an element, for example linear/non-linear spring is capable to introduce a force dependent on deformation.
2/ you can create an loop in APDL which do following:
[ol i]
[li] calculate first load step[/li]
[li] *do,,,,[/li]
[li] get deformations[/li]
[li] calculate new load a apply it[/li]
[li] make restart and solve new step[/li]
[li] *enddo[/li]
[/ol]

The drawback of the second approach is, that you update you load only at end of each load step

There could be also other way but I would need more detail description of your application.

COMBIN37 is a fancy spring element that might work for you.


Kind regards,

Hi, in my problem y have 2 bodies contacting. I want to apply a heat flux in the contact surface proportional to the contact pressure of each node. Is this possible?
