When you connect to the COMSOL server, you may be asked if you want to save your current model.Saving your Model, Disconnecting and Shutting Down from the Server Be sure to set up the forwarding port as:.Refer to our Connecting to your Cluster Documentation.If you are using your personal workstation, you would first need to set up an SSH tunnel to the remote cluster (COMSOL server). If the client is a Rescale Desktop, you will need:Ĭonnecting from your Personal Workstation.If the client is your computer, you will need:.At approximately lines 3,4, & 5 of the log, you can find the server information. Once the log looks like the one in the screenshot below, your server is ready to receive jobs.įrom your process output.log file, you will need the following information to connect to the COMSOL server. Please use the live-tailing section to monitor the process_output.log file. Your cluster will now take a few minutes to spin up. Review the job settings and click Submit.These comprise the compute resources available for solving your models. Here, specify the core type and the number of cores for this server.

This setting will not only let you connect to the COMSOL server but also to any running clusters of your job submissions from your personal workstation.

If it’s a Rescale Desktop you can skip to the next section. If the client machine is your personal workstation, you need to follow the directions in this section.

Generating your SSH key (Required only if Client is your Personal Workstation) Finally, you will use the COMSOL GUI to connect to this server, carry out your workflow, and disconnect/shut-down when finished. Then you will spin up a Rescale Desktop that will directly connect to the server without SSH. You will set up a COMSOL Multiphysics Server in the form of a Rescale Job. If you use a Rescale Desktop as the client: Then, create an SSH tunnel connection in your personal workstation to securely transfer your data to the Rescale-hosted COMSOL server. If you use your personal workstation as the client: You will be able to access Rescale’s cloud computing resources while still using the COMSOL software and graphics in your client machine.
#COMSOL MULTIPHYSICS TUTORIAL EXAMPLE 1 5.4 HOW TO#
The surrounding infinite domain is automatically accounted for when using boundary elements.This tutorial shows you how to use COMSOL’s Client-Server mode of operation in Rescale. The most important benefits with the boundary element method for electrostatics is that there is no need for a volume mesh in the in-between and surrounding air and there is no need to add infinite elements for the surrounding unbounded domain. For the Electromechanics, Boundary Elements interface, the Solid Mechanics interface is based on finite elements whereas the Electrostatics interface is based on boundary elements. Physics interfaces based on the boundary element method can be combined with those based on the finite element method. The backward coupling to the Electrostatics interface is due to the deformations of the boundaries. The coupling is a boundary load on a structure caused by the Maxwell stress at the interface of the solid domains and nonsolid voids, where the electric field is computed using the boundary element method. The Electromechanics, Boundary Elements interface combines the functionality of the Solid Mechanics and Electrostatics, Boundary Elements interfaces to model the deformation of electrostatically actuated structures.
