I am working on numerical simulation of breast model to evaluate the use of thermal imaging for breast cancer detection. To do this I need to construct an ellipsoid rotated 30 degrees around y-axis and cut from x–y plane. The outer major and minor semi-axis lengths of the ellipsoid are set to 0.08 m and 0.05 m, respectively. I am working on Fluent for the numerical simulation and using Design Modeller to generate the model. I need help on how to create an ellipsoid using any 3D CAD software (after which it can be imported into design modeller)
You can draw an ellipsoid in ANSYS DM by following the below steps:
- Select a plane and draw an ellipse. I selected the XYPlane.;
- Using 'trim' (available in 'Sketching'>'Modify') remove half of the ellipse, as shown in the figure below. Note that 'trim' tool is shown on the left side of the figure.
- Thereafter, change the plane. In my case, my ellipse was drawn on the YXplane, and I created a new plane on the XZplane. Draw a circle (figure below).
- Finally, in the Modelling mode, select 'Sweep'. In 'Sweep', specify your half of the ellipse as 'Profile' and your circle as 'Path'. Done!
