SUMMARY

The discussion focuses on modeling heat conduction in a semi-infinite solid using MATLAB. The user initially employed the linspace() command for finite geometries but seeks guidance on extending this to a semi-infinite model. A suggested approach is to define a linspace() from 0 to a large value, such as 10 or 20, to simulate the effects of a semi-infinite solid, effectively treating the far end as theoretical infinity.

PREREQUISITES
  • Understanding of MATLAB programming and syntax
  • Familiarity with the linspace() function in MATLAB
  • Basic concepts of heat conduction in solid materials
  • Knowledge of numerical simulation techniques
NEXT STEPS
  • Research MATLAB's linspace() function for advanced applications
  • Explore numerical methods for modeling heat conduction in solids
  • Learn about boundary conditions in semi-infinite solid models
  • Investigate MATLAB's plotting functions to visualize heat conduction results
USEFUL FOR

Engineers, researchers, and students involved in thermal analysis, numerical simulations, and MATLAB programming who are looking to model heat conduction in semi-infinite solids.

Hello,
Am working on a model that involves heat conduction in a semi-infinite solid. I have been using linspace() command for finite geometry, but now i need to create a 1-dimensional semi-infinite solid. Any suggestions?
Thank you.

In numerical simulations, we can refer to infinity as something very far from the disturbance. In your case, if the heat conduction only takes place e.g from 0 to 1, you can set a linespace from 0 to 10 or 20, and it will effectively work as theoretical infinity would.
