    How to measure the area of individual elements on a model?

    Chris. Thanks for your help. I have found a simpler method of calculating the total area of the face in CATIA then dividing it by the number of elements. There is a slight discrepancy but it is only by around 0.064 for each element face, which I use for discussion.

    How to measure the area of individual elements on a model?

    Yes that's correct Chris. I am not very good at python script at all but do have a friends script that will extract all element nodes on a face and groups them accordingly. Then I have a script that can take the co-ordinates in an ABAQUS model and import them into a CATIA model.Then I can use...

    How to measure the area of individual elements on a model?

    ...quadrilateral is: calculate semiperimeter (s) = (a+b+c+d)/2= 111/2 = 55.5 area is: square root of {(55.5-30)(55.5-31)(55.5-22)(55.5-28)-1/4(30*22+31*28+34*43)(30*22+31*28-34*43)} = Square root of {(25.5*24.5*33.5*27.5) - 1/4(660+868 +1462)(660+868-1462)} =square root of {575550.94 -...

    Finding the stress or strain on each individual node?

    Hello mechfeeney, SENER is the correct output variable that I should be using, the only thing problem is that it is at the integration points and I wish it to be at the nodal points. I am not sure how I would get this to work? Perhaps when setting up the analysis? Creating another step file...

    How to measure the area of individual elements on a model?

    I have an analysed model in Abaqus. Is it possible to measure the area of each of the elements associated on the model?

    Finding the stress or strain on each individual node?

    Maybe I could pose another question to you mechfeeney? Do you know if this is the correct formula to find strain energy density? strain_energy_density = 0.5*von_mises*max_principal_strain Where: von mises has the field output "S" max principal strain has the field output "E"

    Finding the stress or strain on each individual node?

    I have just submitted a model for analysis and got the results odb. I was just wondering is it possible for the analysis to tell me the exact stress or strain of an exact node on a model?

    How to find the strain energy density on a model?

    Is it possible to find the strain energy density of each face, edge and vertex in an analysed model?

    Which elements lie on a particular face

    I have the .inp file from a typical analysed model in ABAQUS. Detailing the element and nodes associated with creating the element, as follows: *Element, type=C3D8I 1, 49, 42, 41, 66, 121, 114, 113, 138 2, 30, 29, 26, 25, 102, 101, 98, 97 3, 60, 48, 33, 32, 132, 120, 105...

    Formatting a .inp file so it easily read

    ...that I want a script in CATIA to read. The problem is that it presents itself in a format which my macro cannot read. An example of this is: *Node 1, 0., 20., 0. 2, -100., 20., 0. 3, -100., 20...

    Find area of face in mm?

    One more question. I'm not sure what the problem is here, but I don't think that the measure tool is calculating the correct area for me. It says 1200mm2 for both faces but 1 face is clearly larger than the other. "Face" contains the correct area of 1200mm2 I have included a screen...

    Find area of face in mm?

    I am trying to work out the area of all the faces on a model. I see you can do this by measure inertia and measure item. The answer always appears in m^2 and rounds it off to 3 decimal points, is there a way to give the exact answer in mm^2 or give the exact answer in m^2?

    CATIA V5 R20 Associative Interface

    I am trying to import a model from catia to abaqus using the associative interface. When I attempt the automatic method nothing appears in the abaqus viewport, when i try the manual method I get the error message: "file may be corrupt or not a valid" "no part and instance was created" I...

    Manual creation of node and element sets in the odb

    Hello, How do I go about manual creating a surface node set and a surface element set in the results output database of an anaylsed part?

    Exporting points from one face at a time?

    Would you be able to tell me how I would go about creating this macro? How do I assign geometric sets to individual faces, edges, vertices?
