CST I-Solver 相关问题！

用I-Solver求解反射式阵列天线，仿真总是提示错误与警告，请问各路大神需要怎么解决呢?我用馈源的farfield-source作为激励去照射反射板。
错误：Inconsistent number of S-parameters. Please delete and recalculate all results with the broadband S-parameter sweep enabled.
警告：Radiated power greater than excited power for farfield. Please check the simulation setup.

Step 1: Delete and recalculate all results with the broadband S-parameter sweep enabled.
Step 2: Check the simulation setup and recalculate.
