Hi @Morteza, when simulating patch antennas with high permittivity materials, it is not uncommon to experience increased simulation times. Here are some strategies to consider for improving simulation efficiency:
- Adaptive Meshing: Implement adaptive meshing techniques to refine the mesh only in critical areas, such as near the edges of the patch or where field gradients are significant. This targeted refinement can reduce the overall number of mesh elements without compromising accuracy.
- Mesh Density Optimization: Evaluate the mesh density settings. While high permittivity requires finer meshing, you might experiment with slightly coarser meshes, ensuring that the results remain within acceptable accuracy limits.
- Solver Configuration: Review and adjust solver settings. Utilize options for iterative solutions, parallel processing, or reduced-order models if available, as these can significantly enhance computational efficiency.
- Material Approximation: Consider using a slightly lower permittivity value if it can approximate the material's behavior adequately for your study. This approach can sometimes lead to faster simulations.
- Frequency Range Limitation: Narrow the frequency range of interest if possible. A smaller frequency bandwidth can decrease the computational burden.
- Boundary Condition Optimization: Optimize boundary conditions to minimize the computational domain. Properly chosen boundary conditions, such as perfect electric conductor (PEC) or radiation boundaries, can help reduce simulation time.
- Hardware Acceleration: Explore hardware acceleration options, such as GPU computing or distributed computing, to enhance simulation speed.
- Software Updates: Ensure that you are using the latest version of your simulation software, as newer versions often include performance optimizations.
- Model Simplification: Simplify the geometry or material properties where feasible. If certain features of the patch are not critical to the study, simplifying them can reduce computational complexity.
By implementing these strategies, you should be able to achieve a more efficient simulation process while maintaining the necessary accuracy.
