如何查看自適應(yīng)仿真以后的網(wǎng)格密度設(shè)置啊
每次自適應(yīng)以后，應(yīng)該已經(jīng)得出了一個(gè)好的網(wǎng)格密度了，我自己如何才能查出當(dāng)時(shí)的網(wǎng)格密度，這樣下次再經(jīng)過(guò)修改某些參數(shù)以后可以不再自適應(yīng)。

Mesh view or Global Mesh Properties

自適應(yīng)仿真以后的網(wǎng)格密度會(huì)自動(dòng)更新至網(wǎng)格設(shè)置，當(dāng)你重新修改模型后，網(wǎng)格設(shè)置是不會(huì)變的。

May argue on this one.
From CST Help file "Mesh Generation Overview":
Refinement strategy
The mesh adaptation process can be carried out by either an Energy based strategy or an Expert system based strategy. The Project Templates activate the Energy based method by default for planar structures.

Energy based mesh refinement
This is the conventional approach to mesh adaptation. While the electromagnetic field simulation is performed, the energy density in the computation domain is recorded. Regions with high energy density and high field gradients are identified, and the mesh is locally refined there.
The amount of refinement per pass is controlled by the Factor for mesh cell increase. A setting of 0.7 means that 0.7 times more mesh cells will be used for the next calculation than were used for the previous one. In other words, the number of mesh cells increases by about 70 % from pass to pass.
This adaptation strategy is a field-based approach that delivers mesh refinement in strategically important regions. The disadvantage of this method is that the refinement regions are coupled neither to the structure parts nor to the global meshing parameters. Parameter studies and optimizations will therefore lead to repeated adaption runs, which negatively affect the overall performance.
Adaptive expert system mesh refinement
The major difference between this strategy and Energy based refinement is that the former adjusts the expert system’s parameters directly. As a result of this approach, the expert system is trained for a particular structure so that the same settings can be kept for subsequent calculations.
The contents of the adaptive mesh refinement dialog box change if the Refinement strategy is set to Expert system based:
The Mesh increment parameter determines the absolute increase for the Lower mesh limit and Lines per wavelength values per adaptation pass.

At the end of a successful expert system based mesh adaptation, CST STUDIO SUITE™ informs you that the expert system has been trained to yield accurate results for this structure. This means that it will not be necessary to start further adaptation runs with this structure since the quality of the mesh will be maintained even if you slightly change the geometry during parametric sweeps or automatic optimizations.
From CST Help file "Adaptive Mesh Refinement (Transient)":
Refinement strategy
Determine here the strategy used for the adaptive mesh refinement. Two different possibilities are available, either based on the modification of the mesh expert system or determined by regions of high field energy in the calculation domain.
Expert system based
Choosing this strategy, the mesh refinement is performed by successively changing the settings of the mesh expert system. This offers the possibility of running the mesh adaptation only once to generate an appropriate mesh line distribution for the current simulation model. This optimized mesh can be used afterwards for further calculation runs with modified parameters (e.g., parameter sweeps or optimization cycles) without activating the refinement process again.
Energy based
Choosing this strategy the mesh refinement is based on the given energy distribution of the electromagnetic fields inside the calculation domain.
