I don’t regularly use COMSOL in my daily work so it is hard to remember all I learned. Part 3: Collecting Results¶. I have a little problem with contact setup: What i want to simulate is a pipe support, that consists of an upper part, (made from a bent threaded rod and a bent flat steel) that is bolted to a lower part (basically a flat steel). Traction, or tractive force, is the force used to generate motion between a body and a tangential surface, through the use of dry friction, though the use of shear force of the surface is also commonly used. Don’t just close the whole terminal, you can close the that command! There’s commands/apps that are. About This Gig. 1 Modelling & Simulation 2: FEA Laboratory 1 Problem 1: Hand Calculation In the spring example below, use a hand calculation to solve the problem. this file was send me by the comsol support,i have worked on a similar problem in 3D with the dimension and velocity near from this example. Introduction. - The Boltzmann Transport Equation (BTE) was solved using the built in radiative transport equation (RTE) module in COMSOL - Simulation results were validated for specular and thermalizing. Describe the geometry and any simplifications. Example: if I am sitting at a stop light and the light turns green, I absolutely know that my vehicle starts from rest as I accelerate through the (now) green light. The fix is to run: C:\Program Files\COMSOL\COMSOL53\Multiphysics\bin\win64\comsolxpl. Metamaterials are artificial metallic structures having, possibly, simultaneously negative permittivity and negative permeability which is called a double negative medium. We develop a mathematical model. The presenter is Duncan Wardle, once head of Innovation & Creativity at Disney.

To help the learning process, there is a streamlined workflow you can follow that is reflected throughout the user interface of the software. To work around this visualization problem, Kinsey completely redesigned the electrical engineering curriculum in 2017, incorporating two-week cycles of simulation labs and hands-on experiments. Geometry is a 2D rectangle representing a long tube with the porous bed in the middle of it. You'll see the percent complete of the total cycle, mini-cycle (0 to 1. Because of the contact, I need to pass the reaction forces and moments back to the robot (by multiplying with the transpose of the jacobian of the end-effector of the robot in order to convert them to joint torques) to include contact effects on the robot. The following case study from COMSOL Multiphysics highlights how Amgen, a biopharmaceutical company, uses a diverse portfolio of multiphysics simulation apps to deal with multiple drug modalities. Best regards, Magnus Ringh, COMSOL. COMSOL, Inc. I have already implemented the finite difference method but is slow motion (to make 100,000 simulations takes 30 minutes). The governing program was created using COMSOL’s application programming interface. On the simulation software it was easy to study how the melt flows and in which part of the die is the shear stress and strain strong and weak. The first thing I did was make a cylinder geometry in ANSYS. The COMSOL discussion forum covers a wide variety of simulation topics.
