    FEA Strand7 model - Truss element

    Amazing! Thank you very much. I also did an excel calculation of this structure. I was wondering why it does not match with my model. Now you helped me spotting my mistake, it all matches now.

    FEA Strand7 model - Truss element

    Hi I have this FEA Strand7 model where a truss element is oriented at 45 degree angle to the beam element. From my knowledge I can say that truss element only takes axial stress. But the model shows that the truss element also response to bending moment when the analysis is performed. Why is...

    Strand7 Error: Global stiffness matrix is singular.

    Thank you retired13 for your reply. I understood what you meant. Let me explain to you the setup properly. "I have a horizontal cantilever beam connected to a bar (at 45° to the cantilever) through a node. A vertical spring is connected to the beam and bar right below that common node." I...

    Strand7 Error: Global stiffness matrix is singular.

    Hi I have this 2D oriented Strand7 model where a cantilever beam is connected to a bar element (oriented at 45 degree) which can only take axial stress(assuming to be a truss element) and a spring at a common node. A force is being applied on that node. Orientation of the elements are shown in...
