Multiple loads on a Face

[djw2k3]

Hi all,

Having recently returned to Algor V18 (from V10) I am getting back to the basics.

Anyway, I am having a devil of a time appling multiple forces onto a face. I want to apply a surface force in X and a surface force in y on the same face.

If I apply a surface force in say x. I then reselect the surface and attelpt to add a load in y but the surface force option is greyed out.

Is there something I am missing? I can't remember this not being possible...

Select custom direction, and then install the x force magnitude in the x direction box and the y force magnitude in the y direction box. There is no need to normalize the vector.

Square the x force and square the y force and add them together. Take the square root of that sum and that is the magnitude of the vectored force.

This should be straight forward if you are an engineer of any discipline. I am surprised that any engineer would ask this question. Note that this web site is for engineering professionals.

Zapster...a little rough. FEA has changed a great deal since Algor was in v.10!

djw2k3, are you applying these loads on a 2-D or plate element? If so, I imagine it is the corner element giving you problems. Split the corner quad into 2 triangular elements so that the loaded edges are in two different elements.

GBor, you are correct. My statement was more than just a little rough. So:

Diw2K3, please forgive my rudeness. It was not appropriate. I had assumed that you simply did not understand the basics of vector mathematics.

Regards,
Zapster

Hi Zapster,

Thanks and no offence taken - have been in these forums for a while and at times I have often thought about writing comments like yours

I had ended up using the vectored solution - I am reasonably experienced mech eng with a lot of FEA experience.

Yes it is a 2D plate element model, I will try your suggestion GBor - thanks.
