@mahesh2444 The GPU will only be used in specific analyses. If you select to enable the GPU, it will be used if possible. It cannot be "forced", it will be used only if supported, and will not be used if unsupported. You can refer to the HFSS Help Documentation for further information on GPU support.Thanks,Matt
