A parametric simulation of an aluminum heat sink used for the cooling of components in electronic circuits. The parameters controlling the geometric dimensions as well as the inlet air velocity are edited in an Excel spreadsheet and synchronized with COMSOL Multiphysics. The postprocessed COMSOL model can be brought into the Excel spreadsheet as a figure.

LiveLink for EXCEL®

Integrating Spreadsheets with COMSOL Multiphysics

The simulation capabilities of Excel® can be augmented by seamlessly integrating them with COMSOL Multiphysics®. Whether you are an engineer with years of Excel data describing your process and looking to utilize it in a COMSOL Multiphysics simulation, or you are a scientist wanting to utilize simulation to find and optimize the value of a material property, LiveLink™ for Excel® will provide you with the flexibility you need.

LiveLink™ for Excel® allows you to take advantage of the capabilities and structured simplicity offered by Excel to extend your COMSOL Multiphysics® modeling capacity. Parameters and variables that are defined and modeled in COMSOL Multiphysics are instantly available in Microsoft® Excel® and automatically synchronized with your physics model. Moreover, LiveLink™ adds the capability to create a COMSOL® material library from data stored in a worksheet and brings it into COMSOL Multiphysics, while also enabling support for loading Excel files for parameter and variable lists in the COMSOL Desktop®.

The COMSOL Multiphysics tab within Excel gives you access to a number of the features and functionalities that are available in COMSOL Multiphysics – such as opening and saving models, importing and re-defining parameters, variables, and functions, running mesh and solver routines, extracting and treating data, and presenting your results.
