what is ARMA? FDTD is not adequate for any simulations where the wavelength is long compared to the object being modeled https://speag.swiss/products/semcad/modules/what-is-fdtd/

Re{Ez,exp(jβ)} is the real part of the z-component of the electric field and RMS{D(x,y,z,f(0))} is the root mean square of the displacement field which is defined as D = permittivity*E. You can change what you want to see in the properties tab of your screen.

yeah,thank you for your help,i realise i can refer to other examples,There is a problem with creating voxels after separating the grid. Access Cheesecake cannot view voxels. I wonder what the problem is and hope you can help me. I can add your email address, so that it is convenient to communicate with you.

hi i guess you could scale the voltage and field in a post-processing step. for that you could measure the current in your simulation (flux evaluator + current density), and then scale your field so the current reaches the desired value. you can also measure the impedance from the measured current.

@montanaro Hi montanaro Thanks for all your help. I got your point in your above script and it works on python.

I am not familiar with SCANIP or it's image formats, but can't you export your data as an stl or another compatible image format? In the 'Model' tab, if you click on 'Imp/ Export' -> 'Import' you should be able to see the different file formats that can be imported. If Exporting your whole model as some compatible format doesn't work, maybe you can export the different tissues individually? If this doesn't work then maybe you can email the support team to request compatibility?

Really late reply, sorry, hope the reply is still useful ... Please check in 'Setup' what you set up in 'Periods' ... For user defined sources, the simulation time is defined by 1/frequency * periods ... So this might be the issue (which should probably be changed if so)

You're welcome! If you haven't found it already, you may also check this post: https://forum.zmt.swiss/topic/8/how-to-calculate-the-inductance-of-a-simple-coil It has useful information for computing the inductances...
