Whay exactly is Wall Force in StarCD?
 

Hi,

we have a small problem with wall forces in StarCD.

StarCD gives us what it calls Wall Shear Forces in N. But what is this value related to? Which Area? I have no Idea, since a local Wall Force in N doesn't make any sense to me. I can have a force as integral of pressure or stress over a surface, but not as a stand alone local value.

So what is it that StarCD calls Wall Shear Force?

Regards,

Torsten

the wall force acts on the area of the shell cell, it will vary from cell to cell. if you have the wall force loaded as cell data then do:

oper getw area 5 oper divi 4 5 4 wplo

then this will give you the stress, if your more happy with that.

Thank you, that's what we figured out in the meantime. We do the calculation as you state it and I'm much more happy with that :)
