Refering to Point Mass using Command Snippet in Workbench 11

[Transient1]

Hi,

If I want to apply a force to a rigid point mass, how can I refer to the point mass in the command snippet? In classic you can apply the force to the node that represents the point mass. I don't see how to get that information in workbench.

Thanks for your help.

Hi,
I don't think I understand your point:
if you are able to create the mass within WB, that means that you have a "hard point" in your model which is adequate for that scope. But in this case I really don't see why you couldn't use the same hard-point to scope your force to.
If, instead, you don't have this "hard-point" in the model, you will have to define it via APDL in the snippet; thus node cration, elem type creation, real constants declaration, elem creation, and force application, will all be "written" in APDL.

Hi cbrn,

Thanks for your interest in my question, but I recently recieved an answer. In workbench, one can't simply click a point mass and add a force. This can be accomplished by the following command snippet:

mass_node=node(xloc,yloc,zloc)
F,mass_node,Fdir,value

The location of the point mass is displayed in the information window for the point mass.

Hi,
"one can't simply click a point-mass and add a force": interesting information, I didn't know that. Never faced this problem until now, but may happen in the future.
Yeah, the APDL commands you mention are therefore the simplest (and maybe the only one...) solution.
