Base COMPONENTS
One of the base components is required to use any other component from other groups (e.g. Ops).
NextFEM export allows to export the current Rhino model to Designer or towards a Server, or even to a .NXF file. This command converts Curves in beam elements and Meshes (no BRep) in shell elements, finally merging overlapped nodes.
Input paramers:
– (optional) Filename: string specifying the path for saving the .NXF model
– (optional) Server: string containing the NextFEM API server address. Default is http://localhost:5151
Output parameters:
– Nodes: list of exported nodes ID
– Elements: list of exported elements ID
NextFEM Live model permits to exchange data with the model opened in NextFEM Designer.
Input paramers:
– (optional) Server: string containing the NextFEM API server address. Default is http://localhost:5151
Output parameters:
– Nodes: list of nodes ID
– Elements: list of elements ID
– Sections: list of sections ID
– Materials: list of materials ID
– SelNodes: list of currently selected nodes in NextFEM Designer viewport
– SelElems: list of currently selected elements in NextFEM Designer viewport
OPS COMPONENTS
This group contains all the possible operations with the model data. Typically, such components requires as input the parameters supplied by the a Base component.
- Element data: takes as input element IDs and returns various information about the elements
- Node: takes as input a list of node IDs and returns a vector with the coordinates of each node.
