Lumerical FDTD – Research Computing Documentation

Created by Keshavamurthy Indireshkumarlast modified on Aug 08, Suppose you have a number of jobs you want to process at once, and you want to avoid typing job submission command multiple times, the simplest way is to put the commands in a shell script and run the shell script instead.

For any help, contact RC using the information available on:. Users are referred to the tutorials on using these tools.

This section is for those who want lumerica, build simulation models and prepare data files using Lumerical graphic user interface on SHARCNET systems using their own licence. Lumerical Mode consists of an eigenmode solver and a propagator describes propagation of light in planar integrated optical systems. Lumerical license server outage: It is assumed that users prepare their simulation files on their tktorial computers with FDTD Solutions and then carry on large scale simulations–being large number of cases or lumfrical size of problems that are not feasible on their computers–on SHARCNET systems through serial farming tutoril parallel processing.


To create a script, use an editor to create a file, say “runsim.

To establish a graphical capable session on a sharcnet Visualization machine, start a remote desktop by clicking the blue icon beside vdi-centos6 on https: Once you are logged in, you can find the available versions of lumerical with:. Retrieved from ” https: If you have a large number of jobs and each of the.

This might affect your work with Lumerical, especially if you using Nomachine NX. Or if your connecting from a linux desktop then run the “ssh -X clustername” command. Note the FDTD engines are the only components that are supported.

This example illustrates solving ‘nanowire. Providing photonic and optoelectronic TCAD device simulation and photonic integrated circuit design products. Lumerical is a suite of software for simulating photonic components, circuits and systems https: Note the examples shown above are not just for serial jobs, it can be used for parallel jobs too.

If you try to run CAD withoutyour own license, and error message box will pop up such as:. Please only use modules in the SEAS tree, i.

The instructions are at:. Some of the information on this page is for our legacy systems only. This section describes howto run fdte compute jobs from the command line useful for testing before submitting a production job into the queue. If you use ssh, this process is likely to be slow you can speed it up somewhat with the compression option, i. From August 8, 6: The page is scheduled for an update to make it applicable to Graham.


Please do not run Lumerical on the login node. The result will be the same as the previous stanza.

You can then use the following batch script:. This will schedule an interactive CAD session. Removing this file should clean the cache of any corrupted Lumerical license information from previous versions, then it will remain to simply recreate the file using tugorial text editor by copying in the following text:.

You can also use tutodial remote desktop NX capability. Please do not run CAD on the login node. This page was last modified on 8 Marchat Users who need to use FDTD Solutions for their model construction and data analysis must obtain their own licences.

To run the simulations 1 to N, as specified in the script, simply execute the command at the command line.
