Point probe??

Hi,

 

Can we calculate certain value (e.g temperature, pressure) at a point with specified coordinate?

Or

did i need to find a node near that coordinate to do the same?

 

Thanks

    I don`t really see a method to input coordinates and find the value at that point, although FEA generally involves calculating values at nodes and interpolating it within the element to find the result values all over the element.

    Hello,

     

    try to create a section cut and measure at the cutting line. It is also possible to create a node path at any section cut. I'm not sure it is possible at any point... try it.

     

    Best regards,

    Hello again,

     

    if you create a curve of the measure, then you can still use the Akima function to convert the results into a spline representation.

    Take a look at the attached picture.

    Hi again!!

     

    I'm using this technique to probe a node temperature.

    And can I plot a graph at this node respect to time (second)?

    This is transient model.

    Hello,

     

    i'm normally analyzing crash problems, so i don't know whats are the results of your type of analysis.

     

    If i create a measure of a nodal result and transfer it to Hypergraph, i get the results / time (explicit analysis). It is not possible with a node path, only with single nodes.

    But a better way is to write out a history file and take this in Hypergraph directly, since i get a lot more of information's and nb of states.

     

    Best regards,

    Mario
