Hi, in fact you are right, an equivalent builder function (with pointers to end nodes) is not available in ChBuilderBeamIGA.
By the way you can implement your own builder inspired to the Euler one, or even modify ChBuilderBeam.h / .cpp adding the new method and send a pull request to GIThub if it is working fine. (I am sorry but these days I do not have time to implement it) Alessandro Tasora On 25/07/2022 10:10, Iason Manolas wrote: Hi, I am experimenting with the different beam models that the library offers. For constructing the beams I use the interface offered in ChBuilderBeam.h . Essentially I want to model structure using beam elements with rigidly connected joints. When I use eg the ChBuilderBeamEuler class and call the following function: void BuildBeam(std::shared_ptr<ChMesh> mesh, ///< mesh to store the resulting elements std::shared_ptr<ChBeamSectionEuler> sect, ///< section material for beam elements const int N, ///< number of elements in the segment std::shared_ptr<ChNodeFEAxyzrot> nodeA, ///< starting point std::shared_ptr<ChNodeFEAxyzrot> nodeB, ///< ending point const ChVector<> Ydir ///< the 'up' Y direction of the beam ); I can do that since I just pass the joint node's pointer as the endpoint of all joint's incident beams and all seems to work fine. On the other hand for the IGA beam elements there doesnt exist a function that takes node pointers as inputs. How do I model rigid joints of IGA beam elements? -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
