Are you using the same product version in both machines? Are you able to run any other simulation files in the workstation that failed?
Please monitor the RAM and CPU and make sure that you have resources available for the simulation (i.e. CPU and RAM are free) and keep me updated with the results. I am inviting @lyap who has more expertise in this regard.
My laptop runs FDTD 2018a (8.19.1541) on Win10, and my PC runs FDTD 2019a r3 on Win7. It is with FDTD 2019a this simulation stuck. Actually there are two cylinders and a base plate in my simulation. The two voxel-based cylinders are imported from a stl file. But if I disable the stl cylinders and replace them with the build-in cylinders, the simulation runs well. I am wondering if there are some compatibility problem of 2019a version with stl file…Pillar_400nm_test.fsp (336.0 KB)
Please use the same versions on both your machine. There has been a lot of changes between these 2 versions. I would recommend using the versions that are available for download from our website. These are the versions we support.
Please completely removed the previous installations first.
Please mark this as resolved if the issue has been fixed. Thank you
Thanks. I tried in another machine with 2019a and it runs well. I assume the best way should be use the latest version of Windows as well as FDTD.
