LiveLink

The following section will show you how to use FEM-Design connection. The connection allows you to dialog with FEM-Design instance on the fly as if you were using the application to perform specific task. The connection links Grasshopper to FEM-Design and, therefore, the methods are applied to the opened model in FEM-Design.

You can download the Grasshopper definition used in this tutorial from here 👉Grasshopper Definition

caution

• The tool CAN NOT be use to perform iterative analysis (i.e. Galapagos).

note

The LiveLink components use the GrasshopperAsync methodology implemented by Speckle.

The async component, however, might create some error if not use carefully. Our suggestion is to connect the component as shown in the picture below.

The flow is clearly stated and the methods will be called in the right order.

Connection

Connection opens a specific instance of FEM-Design that will run the methods.

Open model

Open a model on an instance of FEM-Design.

Get model

Get the current opened model from FEM-Design instance.

Calculations

Run analysis

Run design

Results

Get FEA model

Get load case and combination results

Get stability results

Get quantities

Get results from bsc

While we provide some ready result types to be extract (i.e ResultType), it might be that you want to extract some specific results that they have not been implemented yet. In that scenario, you can use the batch .bsc file which will inform the software to give you back the desired results.

If you want to create the .bsc file, you need to:

• Open FEM-Design
• Click on Tools
• Select List... (TAB)

You can now select the results that you want to extract and create the .bsc file that you can use in the Grasshopper component.

Configurations

Set global configurations

SetGlobalConfigurations defines the calculation settings that will instruct FEM-Design in operation like creating the finite element mesh. The API provides a set of components and a preset file that you can modify to fullfil your need. However, most of the structure can be analysed with the already specified values.

Using specific components

Preset file

The default global configuration file can be accessed from the following path:

%AppData%\McNeel\Rhinoceros\packages\7.0\FemDesign\cmdglobalcfg.xml

To access FEM-Design -> Settings -> Calculation, you need to use a specific XML file that contains the commands to control the global calculation configurations for Soil, Mesh and Peak Smoothing. Below is a fully prepared file with some guidance, called cmdglobalcfg.xml which contains the default settings for the software. The current approach is to modify this text file with the desired values.

cmdglobalcfg.xml

        fThFicBeam = "0"
        fThFreeEdge = "0"
        fThRegionBorder = "0"
        fThSuppPt = "1"
        fThSuppLn = "0"
        fThSuppSf = "0"
        fThEdgeConn = "0"

        fAutoRebuild = "1"
        fAutoSmooth = "1"
        fAutoCheck = "0" />
    <peaksm_method
        sPeakFormFunc_M = "1"
        sPeakFormFunc_N = "1"
        sPeakFormFunc_V = "1" />

        fPeakSuppSf = "0"
        fPeakConnPt = "0"
        fPeakConnLn = "0"
        fPeakConnSf = "0"
        rPeakFactor = "0.5" />
</cmdglobalcfg>

For example, if you want to change the general mesh settings to enable Adjust mesh to load positions, you need to set the fAdjustToLoads attribute to 1 (true).

    <mesh_general
        fAdjustToLoads = "1" />

Or, if you want to change the lowest minimum division number of bar elements to 10, you need to set the sDefaultDivision attribute to 10.

    <mesh_elements
        fElemCalcRegion = "1"
        rElemSizeDiv = "6.0"
        fCorrectToMinDivNum = "1"
        sDefaultDivision = "10"
        rDefaultAngle = "15.0" />

Most of the XML attribute names reflect the functionality of the FEM design settings. The attribute value types are logically the same as when you set them manually in the GUI. For example, the attributes corresponding to checkboxes are Boolean parameters, so their value can be 0 or 1. If you have to specify a number using the GUI, this means that the attribute value will be an integer or a double, depending on the case.

tip

Keep in mind:

• attributes beginning with 'f' must be 0 or 1
• attributes beginning with 'r' are double numbers
• attributes beginning with 's' are integers

Set design configurations

SetDesignConfigurations defines the calculation/design settings that will instruct FEM-Design in setting up the parameters to perform calculation/design check. The API provides a set of components and a preset file that you can modify to fullfil your need.

Steel design parameters

Steel design configuration

Steel calculation parameters

Concrete design configuration

Preset file

SetConfigurations defines the design parameter configurations. Parameters can be set using a preset file located at:

%AppData%\McNeel\Rhinoceros\packages\7.0\FemDesign\cfg.xml

Alternatively, you can use specific components built to customize the settings.

To set up design configurations using a preset file, we have the same solution as for the global configurations. Config input instructs FEM-Design to apply the design parameters to perform structural check and design. The preset file approach involves modifying the cfg.xml file with the desired values.

The xml file above contains a wide range of design configurations. The comments within it can help you to identify which attributes you need to change to control the design settings.

For example, if you want to disable Steel design configuration -> Use Method 1, you need to set the sInteraction attribute to 1.

    <!-- EUROCODE STEEL CONFIG -->
    <CONFIG sInteraction="1" type="ECSTCONFIG"></CONFIG>

Or, if you want to limit steel utilization to 95%, you need to set the LimitUtilization attribute to 95%.

    <!-- DESIGN PARAMETERS STEEL BAR -->
    <CONFIG LimitUtilization="0.95" type="CCDESPARAMBARST"  vSection_itemcnt="24"></CONFIG>

If you are only interested in Steel bar, you can just use the steel design parameters and omit the others.
