Difference between 32-bit and 64-bit FDTD

Hi, I am trying out the free 32-bit FDTD. Is there any difference between the free version and the 64-bit version beyond that the 32-bit is core-limited and much slower..? Thanks!

    Hi, you can find a comparison table and some highlights of differences on the following webpage:

    Hello

    yeah, i just explained in general terms the advantages

    thanks for the link

    regards Luis

    The link shared by Aurelien Duval provides a comprehensive technical comparison of the two versions of FDTD.

    I can furthermore add an important detail that wasn’t included in that link: Any work you do with the 32-bit version will not be compatible with the 64-bit version, and vice versa.

    Therefore, I would review the details in that link to decide which version suits your needs before starting the modeling process.

    The most important difference between these two simulator types is the memory limitation imposed on 32-bit simulators. All the 32-bit applications may utilize up to 2GB-4GB of memory for its purposes, dependent on the operating system.

    the main difference between the 32-bit and 64-bit simulations is that 64-bit simulators are capable of processing much larger designs. Due to the amount of data volume processed and generated by 64-bit simulators, the approach to the simulation result handling has changed.
