The Material Export Settings dialog box allows you to create a material library accessible by COMSOL models from material data you have stored in an Excel file. The equivalent cells in the Excel file are called from the material and property range edit fields.
A COMSOL Model window is opened when running and solving models from the Excel interface to show the geometry, mesh, and postprocessing views of your model, along with the progress of the solving process.
Model of the Joule heating of a busbar where a parametric sweep is run over the operating voltage. Tools from Excel are used to plot the temperature versus electric potential relationship. The temperature profile along an edge, at different voltages, is also plotted by extracting data from the COMSOL Multiphysics model.
Working with Excel® in the COMSOL Multiphysics® Environment
LiveLink™ for Excel® provides tools to import data directly into COMSOL Multiphysics for further use in the modeling workflow. This can include importing several of the model definitions like parameters, variables and functions, from a worksheet. Furthermore, with LiveLink™ for Excel® you can create a material library within Excel and configure the export in such a way that COMSOL Multiphysics recognizes the material properties and stores them appropriately in your Material Library. You can export results to Excel, where you can compare, optimize, and calibrate these material properties.

Working with COMSOL Multiphysics® Models in the Excel® Environment
LiveLink™ for Excel® lets you perform and control your COMSOL Multiphysics modeling from an Excel environment. When LiveLink™ for Excel® is installed, a COMSOL Multiphysics tab is immediately made available in the Excel ribbon.

With the provided COMSOL-specific icons in the Excel ribbon, you can control most of the steps in your modeling process. This includes 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. Parameters are automatically synchronized with cells in the Excel worksheet, and they can be changed on-the-fly and re-synchronized, and the model can be solved again. Moreover, you can augment your COMSOL modeling with some of the tools and functionality provided by Excel. For instance, columns of data in the Excel worksheet can be used to define the point coordinates for evaluations to be performed based on the model solution. After the evaluation, extracted results will populate related Excel columns, and you can achieve curve-fitting of the extracted data by using tools from Excel.
When you open a COMSOL model from Excel, a specialized graphics interface, known as the COMSOL Model window, is made available. This allows you to track the progress of the actual modeling being controlled from Excel as it displays the model geometry, mesh, and result plots. The solvers' progress and other model information can also be viewed here. The COMSOL Model window represents a COMSOL server application running in the background, where the model is loaded, and you do not need to have COMSOL Multiphysics open in the background to be able to manage your modeling from Excel. Additionally, LiveLink™ for Excel® provides seamless integration so you can insert your COMSOL Multiphysics graphics, along with your other figures and tables, to produce a complete worksheet presentation.
