Can I use the PDE toolbox to solve a heat transfer problem with 1 moving part?

My problem is like moving a iron plate in water and then out again.

I saw this http://nl.mathworks.com/examples/pde/mw/pde-ex30125242-solving-a-heat-transfer-problem-with-temperature-dependent-properties?s_tid=srchtitle But there is nothing moving in this example.

Does your geometry consist of many parts with 1 moving part or just a single part that is going in and out of water?

If your case is the latter, I'd suggest that you represent its movement by time-dependent boundary conditions considering the moving coordinate fixed with the part.

It's '1 moving part' like a plate that is moving on a conveyor moving through water.

Based on your answer I assume it will be possible.

Thanks for clarification! Yes, it's technically possible but please note that the validity/accuracy of the simulation will depend on how you model the boundary conditions.

The problem could be modeled using the Dirichlet boundary conditions, just like the example you mentioned above: fixed temperature. It could as well be modeled using the Neumann boundary conditions that specify the heat transfer across the boundary.

Hi, if i see example code like the link above, how do I know which toolboxes are used? Can I assume it's Matlab and PDE only, or will I get a surprise warning that I need to buy something else also?

[michio]

For the specific example above, it requires MATLAB and PDE Toolbox only.

Usually the toolbox itself, MATLAB and (if anly) add-ons listed as a requirements (See Add-On Product Requirements & Platform Availability for R2016b) are required to run the example on the documentation. I believe it would state explicitly if it requires anything else.

Michio is right. At this moment you, the examples in the documentation will also inform the users about the required toolboxes. Eg. the following example from the Statistics and Machine Learning toolbox also requires Matlab Coder (trial/license needed to access the link) https://nl.mathworks.com/help/releases/R2016b/stats/examples/c-code-generation-for-image-classifier.html
