symbolic operators in functional discription of load

[ptc-212288]

Hi all,

I'm working in WF Mechanica 3.0 stand alone.

I would like to know how to use the logical operators in the load function definition form.

Example: How does one apply 5*ypsi on a surface for y < 10 and 3*y^2 psi on the surface for Y>=10?

Thanks

Joe,

One option would be to create surface regions that occupy these
different locations and apply each different function to the proper
surface.

Hi Joe,

Good to hear that there still are some still using Independent Mode! (Boeing et al.)

Create a Pressure load using Function Of Coordinates, enter this for your Symbolic Definition:

if(y<10,5*y,3*y^2)

and use 1 for your P pressure. Click Review to confirm your function.

But note that when y = 10, your load pressure is discontinuous. Is this what you want?

Hope that helps,
Ray.
