when i i want to simulate near field in MWS CST,i run the transient solver, it said ''The monitor 'e-field(f=10;z=10)'is outside simulation bounds and will be ignored.'' how can i change the simulation bounds?
thx unfortunately i already choose the open (add space),bt it still doesnt work .the boundary can not include the e field at 10cm far away.if i change the meshline to 40 it said this software can only allow 3000 mesh. can someone help me ???how to do it when i want to add a 10cm far away e field to simulate .plz
well if i am not wrong you are simulation frequency is 10GHz and you are putting your e field monitor at 10cm which is about 3 * lambda away from your structure
so i dont know why u are saying your are measuing near field?
its definitely farfield
also it seems you are using educational version of software thats why number of mesh cells are limited.
