    add multiple elements to multiple groups automatically

    Hi, Not that I know of. I wrote this API a while back to do just that, but never found the functionnality that useful so I didnt push further... AP Sub Main Dim App As femap.model Set App = feFemap() Dim l1 As Long Dim grSet As femap.Set, gr As femap.Group Set grSet =...

    How to select correct Femap instance using API

    Hi, Do you mean different models? Here's what the API can do: for one FEMAP instance with multiple models/windows in it, you can retrieve all opened models. Check out Help > 3.16.1.6 feAppGetAllModels. Then you can retrieve the models' names, put them in a droplist box so the user can select...

    6066 Laminate Min SR

    Hi, Look for "NASTRAN Section1 Composites" in a web search engine. You should get MSC NASTRAN's "Introduction to composites" presentation. Look for the failure theories. Most of them require solving a 2nd degree equation => min strength ratio is the lowest solution. There is a trap: I think in...

    selecting tet10 for solid meshing

    Hi, Tet10 is the default, most FEA software won't orient the user towards tet4 which are frowned upon in the mecanical world. If you want to make sure FEMAP will build parabolic elements, when you create the property, and click on the "Elem/Porperty Type..." button ==> look at the top of the...

    Material orientation

    Hi, You are mixing 2 things: - the "Modify > Element > Material" command deals with elements which can be oriented at component level (i.e. at element level), so in the element NASTRAN card. - solids are orientable through their property, not through the CHEXA card. So you need to use Modify >...

    FEMAP layers vs groups

    Hi, I'm not a layer user but here a few tips: 1) multiple groups can be displayed, starting from FEMAP v10.3 or so developpers added the "Show Multiple Groups" capacity 2) I don't get "a layer can only have one entity vs group can have as many entities". Layers have a smany entities as you...

    Stiffened Plate output

    Hi, Yes, starting in FEMAP v10.3 (or maybe v11), in the "Select Post Processing Data" window (the "{}" button) you have the "Multiple Contour Vectors" button, which is thought out for this: plotting results on different types of elements. Be advised though: if you select 2 vectors on the same...

    API - retrieving an array from a Femap command

    Seif's answer is correct: if you're coding in .NET you need Dim s_normal as Object Don't dimension it. Usually in .NET I need to add "s_normal = Nothing" in loops, prior to the function call, because once the method has been called once the object has a dimension. Example (in Visual Studio)...

    How to copy elements from one coordinate system to another coordinate system in FEMAP

    This might help, wrote it a while back. Launch it in the API window. This macro will do the following: 1) ask you for a selection of elements you want to copy Internally it will retrieve all nodes used by these elements 2) ask you for the original CSys 3) As you for the destination CSys...

    Femap API code, Groups from Layers

    Hi, Your problem is that you clear the set but not the group! Think of the group as a "set of sets", or rather a double vector with a rule on one side, and a list of IDs on the other. You never clear you group therefore the surfaces are cumulated in it. The easiest way to do this is to re-set...

    Composite plate (different layer thicknesses)

    Hi, Yes what you describe is possible. If you are a beginner with NASTRAN let's take it back a bit: there are different levels/steps when defining laminate composites in NASTRAN: 1) individual ply/core material: this uses MAT cards, up to you to choose between isotropic (MAT1), orthotropic...

    Honeycomb panel - Modal analysis

    What you describe can actually be done 4 ways: - full 2D + PSHELL: derive equivalent PSHELLs for your panel properties. In the end this is what NASTRAN does anyways (with an echo = PUNCH you can retrieve the equivalent PSHELLs) - full 2D + PCOMP: your 1rst solution - 3D + PCOMP for laminate...

    feRenumberOpt

    There are workarounds, depending on how you prefer your code to work. Perhaps the trackdata object works when renumbering, I've never tested that scenario. But the underlying concept is the same: you could use a first set with all elements for ex, then renumber, then make a second set with all...

    feRenumberOpt

    Hello, I'm on v11.1.1 and don't have the problem you describe. For example create a new model with only one element and run the code below. For me FEMAP returns 1 then 10000, therefore the ID has been updated. Sub Main Dim App As femap.model Set App = feFemap() Dim el As...

    Using Check Sum Forces in API

    A little insight into (what I understand of) FEMAP's API logic: when you select entities (nodes, elements, loadcases...) you want to end up with a list of IDs, not a list of objects. That is a set! So the moethod you're thinking of is a set method, not a loadcase method. You already applied this...
