Bidirectional Interface to Autodesk Inventor
Boundaries with applied positive potential.
Cylinder representing the surrounding tissue.
The bidirectional interface always transfers the geometry in the open active document in Autodesk Inventor.
In the COMSOL Multiphysics Model Navigator select the Conductive Media DC application mode.
In the COMSOL Multiphysics GUI select File>Inventor Connection>Initialize to transfer the geometry and initialize the connection between COMSOL Multiphysics and Autodesk Inventor.
When the transfer is ready the geometry appears in the COMSOL Multiphysics GUI.
Use the drawing tools in COMSOL Multiphysics to create the geometry for the surrounding tissue.
To evaluate the total resistive heat in the tissue define a variable in the Subdomain Integration Variables dialog box.
Set the material properties in the Subdomain Settings dialog box.
Define the electric potential and grounded boundaries in the Boundary Settings dialog box.
Click the Solve button to solve the model.
Slice plot of the electric potential in the tissue surrounding the electrode.
Use the Plot Parameters dialog box to plot the resistive heating in the tissue.
Position of grounded region.
Size of region where positive potential is applied.
To find out the name of parameters in the Autodesk Inventor GUI edit a sketch.
In the sketch, double click on a dimension to edit it.
The parameter d12 is the radius of the sphere which we would like to update through the interface.
Click the Return button to leave the sketch.
Select Parameters on the Part Features panel.
Click Add to enter a new user parameter.
Define the parameter radius, with the value 0.5 mm.
Link the radius parameter to d12 by typing radius in the Equation field of d12.
The other design parameter, the position of the grounded region is d14, which is also found in Sketch1.
Control the value of d14 directly through the bidirectional interface.
In the COMSOL Multiphysics GUI select Constants from the Options menu.
Enter the constants radius and d14 and their new values 1 and 12, respectively.
During update of the geometry these constants will be transfered to Autodesk Inventor to update the corresponding parameters.
Select File>Inventor Connection>Update to transfer the constants to Autodesk Inventor and to transfer back the updated geometry to COMSOL Multiphysics.
When the transfer is ready the updated geometry appears in the COMSOL Multiphysics GUI.
In the Autodesk Inventor GUI the parameters and the geometry have been updated.
Click the Solve button in the COMSOL Multiphyiscs GUI to obtain the new solution.
Select File>Inventor Connection>Geometric Parametric Sweep to set up and automatically solve the model for a range of geometry parameters.
Enter a name for the log file and list the variables to be evaluated.
Enter a list of geometry parameters, and a range of values
Click Solve to start the sweep.
You can also select to save each solved model file separately.
