I am working on Non-Isothermal PE-100 pipe extrusion. I am applying cross law for viscosity dependence on shear rate and Arrhenius law for viscosity dependence on temperature in direct extrusion at POLYFLOW. When i run, it shows solution is not converge. When I change the viscosity to be not temperature dependent, then the solution can be converged. So there is any way to make it converge and in the same time take the temperature into account to determine the viscosity? where I am wrong? I am struck here. Kindly help me.
I need you to create a structural topology optimization code using the FEniCS Package, preferably the sensitivity calculated using Dolfin Adjoint. This code should perform two dynamic problems: Free Vibrations or eigenvalue problems; and Forced Vibrations. The SIMP approach should be considered. The code must generate in addition to the final design seen in Paraview, it must show all iterations, the Compliance X Iteration X Volume Reduction graph and also the Natural Frequency X Iteration graph. All for at least the first three modes in modal analysis, and in forced vibration considering established frequency ranges. References: BENDSOE, M. P.; SIGMUND, O.

I would like to deturmine how air moves around a room that has an fan placed in the corner of the room at ambient temperatures. The room will be set out as a single occupancy bedroom. The fan will be at ceiling heigth and flow continiously. The engineer MUST be able to model the room and add the air temperatures and fan flow rates to demonstrate using the model how the air moves within the space. This is the first of 4 projects of this nature. I do not want a 3d animator. this must be conducted by an engineer with HVAC, Anysis and aerodynamics modeling. I am looking for the results similar to those shown in the example file attached.
