Creating a field that varies through space and time

[wmoonw]

Hi, everyone,

I am a little new to Patran, so I am not too sure of myself; hope this isn't too basic.

I am trying to apply a heat flux to a surface, and I want the heat flux to vary by position in space (X, Y, Z) and time. I have found ways to vary it by just position and just time, but I can't seem to get all of it.

Does anyone have any recommendations or suggestions? Thank you!

For that one i'd give MSC support a call. It may just be possible, but i cant think off-hand (after a bottle of wine) whether it is or not.

If anyone stumbles on this with the same question, I figured out a way around this problem. It's not prefect, but it's a workable solution. . . .

If you can use Nastran as a processor and use a transient load case, it lets you use two different functions to represent space and time, and it multiplies them. You can apply two different fields, a spatial one and a nonspatial, time-based one, and apply them both.

Again, it's not an elegant solution, and it won't work for all cases, but it'll do for some problems! If anyone comes up with a more elegant way of doing it, please let me know!
