COMSOL image to Geometry: This add-in allows you to utilise a picture as the starting point for your analysis with the Image to Curve add-in. A contour plot of an imported picture is used to generate an interpolation curve, which is produced using the add-in. Afterwards, this interpolation curve may be utilised as part of a geometric model. In this section, we show how to make advantage of this feature.

Creating the image
We created the image in PowerPoint for our demonstration you can use any other image or shape for this purpose.
Install image to curve Add-in
The Image to Curve add-in may then be enabled from the libraries by selecting the Developer tab and then Add-in Libraries.An image may be a photograph of an item or a sketch. The following image formats are supported: .png, .jpg, .jpeg, .bmp, and .gif. The picture should ideally be a dark form on a brighter backdrop or a light shape on a darker background in order to produce high-quality geometry. When a colour image is imported, it is always converted to grayscale.
Advanced settings
Reduce noise (blur) or sharpen edges (sharpen) in the imported picture using these filters. The form of the curve derived from the picture will vary when the filter is changed. A Gaussian blur filter is used by default. Use specialised image processing tools to further process the picture before importing it if necessary. To render the original or filtered picture, click the Plot or Filter buttons on the toolbar, accordingly. There are few other settings too which could be explored easily.
Import image & create curve
Click on the curve feature to generate the curve as interpolated curve
COMSOL image to Geometry
Here you can see the geometry extruded like any normal 2D geometry in COMSOL from the image. Follow the youtube tutorial linked above for detailed explaination.
