Shear forces

[Favollo]

Hi there,

what is the quickest way to apply a distribution of shear forces over a surface?
Ideally I want to apply a shear force constant in direction tau ij = f (x,y). i.e. the magnitude is a function of the node position.I have the same problem if I wanted to apply a displacement field dependant on the position.

Would be grateful for any help.

Regards

Marco,
Four letters...APDL. You can either use a Table to define your force or have the force be depended of x and y and loop through applying all the nodes on that surface applying a force to them which depends on their coordinates. You may need to definie a local coordinate system to do this.

I don't have time right now to write a sample macro up as I'm studying for exams. Look on ansys.net and you should be able to come up with something. Are you familiar with APDL at all? You'll need to be somewhat versed on this to do this task unless you're using the latest release of WB. I'll see if I can dig up a sample snippet of code from a macro at work.

Stringmaker,

thanks for your answer.I suspected I should have used APDL, that is why I was looking for something else..
Anyway, good luck for your exams.
