    Abaqus - Extracting Forces from Ties

    Does anyone know if it is possible to extract the force that is transferred via a tie constraint? Similar to the glue force output that NASTRAN has?

    Have Force Point at Fixed Anchor Location NLGEOM Simulation

    In the rare event that anyone else has similar question, I got this answer on the 3DSwym SIMULIA forums that is working quite well. "Define a fully constrained reference point at the location of the anchor point and connect it to the beam with a connector element. Then you can prescribe the...

    ErrElemAreaSmallNegZero when using shell mesh

    I would check to see if any of your interactions have the "adjust slave initial position" option turned on. I have had the issue where this option was inadvertently turned on, and the adjustment caused some elements to collapse, resulting in the same error you're getting.

    Have Force Point at Fixed Anchor Location NLGEOM Simulation

    I am working with a geometrically nonlinear simulation, and I'm trying to have a nodal force consistently point at a fixed anchor point, as the model deflects. Using the default CF options doesn't achieve this, as the force consistently points in the same direction, and doesn't change to point...

    Abaqus Nonlinear Riks Buckling - Determine If Local Buckling Occurs

    Unless I'm missing something, plotting deformed shape in and amongst itself that doesn't tell you if buckling has occurred. I agree it should be done as a model sanity check, but a panel could have a large out-of-plane displacement with the P-u curve being totally linear.

    Abaqus Nonlinear Riks Buckling - Determine If Local Buckling Occurs

    Hello, Quick question. I'm examining a stiffened box beam subjected to axial, shear, and bending loads, modeled with S4 shell elements. I've run a nonlinear Riks buckling analysis, and have set the termination criteria to be my expected worst case load proportionality factor. At this load, I'm...
