The residual norm on the displacement is a factor 10^ lower than the initial value.The number of iterations in every time step is larger than 20.Two convergence criteria have been specified: ![]() The initial guess in every time step is done using the linear predictor. The coupling technique used is the interface quasi-Newton algorithm with an approximation for the inverse of the Jacobian from a least-squares model (IQNI-LS). This done by using Fluent (3D case) and Abaqus (axisymmetric case). This example calculates the flow inside and the deformation and stresses of a straight flexible tube, where a pressure pulse is applied at the inlet.
