I am adding an aluminium with a rough surface in CST Studio, but there is only thickness input (how thick the rough surface is), but as per ISO standards they are different types of rough surface with RMS (rms) 2200, 1100, 550 etc.
In CST Surface roughness (rms) is given but they didn't specified or asked for the rms input.
I'm not sure what your problem is. The table gives RMS roughness (in microinches) and CST requires RMS roughness (in mm). The only thing left is for you to find out or decide which grade to choose and fill in the box.
Look for it in the parameters, it must be mentioned somewhere and often it is on Micron. For HFSS is clearer.
In my version of CST I can type any value I want into the RMS surface roughness box that you have outlined in red, can't you?
Hello,
In my CST software, RMS surface value is clearly visible. Just change the unit, which is required.
CST is full complete package, check the CST help file.
Thanks,
