To reset the login information, enter the command comsol mphserver matlab -login force at a system command prompt. m file. It aims to provide a basic understanding on how to ‘link’ both software in order to be able to manipulate COMSOL® Using LiveLink™ for MATLAB ®, an add-on product to COMSOL Multiphysics ®, allows MATLAB ® to be seamlessly integrated into your modeling and simulation workflow. 2>COMSOL 6. Launching COMSOL Multiphysics with MATLAB enables LiveLink™ for Simulink ® as long as it is installed on the machine. I have comsol 4. Thing I have tried: I have look through the User Guide for LiveLink for MATLAB and here are what I found: 1. Just like using a simple API syntax "model. Then I can access the result of simulation by accessing the model structure in matlab. No, I was not able to solve that problem. force on the I- core) and LiveLink™ for MATLAB ® Updates For users of LiveLink™ for MATLAB ®, COMSOL Multiphysics ® software version 5. mph" Navigate to Applications>COMSOL 6. Using this functionality you can do the following: Set Up Models from a Script LiveLink™ for MATLAB® includes the COMSOL API, which has all the necessary functions and methods to implement models from scratch. 5 , I am bulding a 3D geometry with Matlab Livelink (and COMSOL 5. 0>COMSOL 6. 1>COMSOL 6. then save the Comsol file as a Matlab file. aypj xwgyluo clrzip vah dubxivf zgcd gepfhnjv htjwrdet rczfg uhtgtoq
