Adaptive meshing techniques refer to numerical methods that adjust the mesh or grid used in computational simulations based on the characteristics of the solution being modeled. This allows for finer resolution in areas with complex behavior while using coarser meshes in regions where the solution changes less dramatically, enhancing computational efficiency and accuracy.
congrats on reading the definition of adaptive meshing techniques. now let's actually learn it.
Adaptive meshing techniques optimize computational resources by refining the mesh only where necessary, which is particularly useful in terahertz device simulations where electromagnetic fields can vary significantly across space.
These techniques are crucial for accurately modeling terahertz devices because they allow for better resolution of critical features such as resonances and field distributions without a dramatic increase in computational cost.
By employing adaptive meshing, one can dynamically adjust the mesh during simulation runs, providing an efficient way to handle non-linear problems that change over time.
