define a point to trace its unsteady pressure
 

hi max and all

I can define a point to monitor its unsteady pressure by using the surface-point command in a 2D model.But failed in a 3Dmodel.


the error message is ''surface creation failed!''.

so what should I do to define a point in the 3D model?

thx in advance

Be sure that the point you defined is in your model.
You can return to gambit, create your point and checking that it's ok.
I just created a point in Fluent 3d, and it is ok

yeah I just tried what you say

it works.

it turns out that the point you defined should around the nodes or it will fail

thank you :)
