  I drew antenna with lumped port exitation, and solution 10 GHz(interpolating 1-10 GHz) . After the simulation starts, it stops with error "as simulation completed with execution error on server"
  
  When the simulation is in "HFSS starting" , it stops.
  
  Is it about unnecessary Ram?

  HFSS has some init bugs, some appear, some get fixed in newer versions. Many of these are related to previously solved data and mesh in the project data folder. Sometimes, the bug is in XML itself (it is not properly cleaned when editing old projects, and a lot of garbage accumulate there)ntry deleting the solved data directory before loading the projectnIf it does not work, try creating a new clean project and copy-paste (yes, CTRL+C -> CTRL+V) all the objects there. After that copypaste the report setup. Enable Duplicate boundaries/mesh operations with geometry in tools-options-general-HFSS-boundary_assignment for reducing work amount.n

  nThank you for reaching to us and we appreciate your patience.nThe error says that the HFSS solver failed to start. Did you run the validation check before analyzing?nAll the very best.n
