How to enter Pressure field in Patran?

[gravig]

Hi,
I have a dataset of more than 300 pressure pts in X,Y and Z coord. And I need to input this pressure field on my elements. However, these pressure pts might not coincide with my meshing (node pts or element surface).

I already read thread824-106551 , but it isn't complete, since it doesn't explain how to create the pressure field and above all how "create a new field based of the CFD field
and project it on your FE structural model" (step c).

Please help me.
Regards.

I'm not totally following you, you say that your tying to apply a pressure to your model, but the pressure isn't applied to your structure?? Could you try to explain a bit more about your model? Maybe you could just apply the pressure to a geometric surface.

Yes, I have my FE structure (with a quite fine mesh), and
I have to apply a variable pressure field which was provided through a CFD software: my problem is that this software can provide only a cloud of points coordinates, and their corresponding pressure values.
Note that CFD model has a large mesh, very different from my one, but on the same surface (more or less....).

Is possible to apply the pressure directly on the surface?

How can I "import" the provided discrete pressure field into Patran?

Thanks
