    How to plot phase of realized gain of antenna pattern in HFSS like CST Software

    Thanks. that's right I knew how plot Gain of antenna in HFSS. I want to know how to plot "phase of pattern" in HFSS. As you can see in CST results. Attached file shows the image of result in CST (plot theta phase of pattern)

    How to plot phase of realized gain of antenna pattern in HFSS like CST Software

    Hi Can anybody help me to make plot of phase of Antennas' Radiation Pattern in HFSS? in CST Studio software, Farfield results, plot "theta phase" and "phi phase" of realized gain of Antenna pattern. How we can plot phase pf pattern in HFSS like CST? Thanks

    link between ANSYS and HFSS

    Dear perejferrer Thank you very much for your response. it was very helpful for me. if I do not change mesh, will the result mistake? (e.g, the scaling factor is 2) in addition, to define radiation, is it important for structure? my design work under natural convection. and How I can define the...

    How to perform power handling analysis with Ansys HFSS

    Hi Paolo, to perform power handling test on an eletromagnetic structure in HFSS, you must define the value of your power in the port1, then show the field distribution on structure, as you know the maximum electric field shows in V/m. you must khnow the breakdown voltage of each materials you...

    link between ANSYS and HFSS

    I have a question about the ansys software. when we link HFSS with Workbench of ansys (thermal static) , the imported data from hfss show scaling factor in addition of surface loss density. i would like to thanks if you tell me what is the concept of scaling factor? should we multiply the value...

    calculate thermal cresistance of heatsink

    thanks a lot for their answer. but i have know how calculate thermal resistance in terms of physical characterize and independent of temperature or power dissipated or without testing, when the length of heat sink is changed as shown in many company e.g. Fischer electronic. it plot thermal...

    calculate thermal cresistance of heatsink

    Hi every body i have a question about how can calculate thermal resistance of heatsinks under natural convection air and forced air (both of them) if the equation independent of temperature and depends to physical dimension of hestsink. thanks

    how to change incident power in HFSS

    hi. thanks for your attention. in hfss , voltage determined in Edit source. then we should write voltage no power. in hfss Edit source v=1 then i think the power couldn't 1watt. i think hfss help had mistake.

    how to change incident power in HFSS

    hi, I have a problem. i want change default power (1w) in hfss. i know that is in Edit source/scaling factor in hfss. but i don't know how to change value scaling factor. i mean i want power 20kw, so what value I write this tab?:cry: thanks for your help

    how to select the substrate

    thanks for reply my ask. i visit the McMaster site for polyethylene, but i couldn't find relative permitivity (er=?) of material. is there er=10.2 ? and what is reason for select slab plastic? is there "er" for this? i embeded bar metal (like stub short circuit) in coxial cable...
