Tutorial: running COMSOL on the TRITON Cluster

Staff trainings, Training to support research, Students
COMSOL is a powerful tool to solve many physics and engineering problems. However, often the resources of a single workstation are not sufficient to solve large models or test many parameters. These limitations can be overcome by running COMSOL simulations using high performance computing (HPC) resources.

Tutorial: running COMSOL on the TRITON Cluster

COMSOL is a powerful tool to solve many physics and engineering problems. However, often the resources of a single workstation are not sufficient to solve large models or test many parameters. These limitations can be overcome by running COMSOL simulations using high performance computing (HPC) resources.

Radoslaw Kolkowski (Academy Research Fellow from the Department of Applied Physics) will give a tutorial on best practices for running parallel COMSOL simulations on Triton - the Aalto University computing cluster.

Agenda

  1. Getting started​
    • Connecting to Triton and setting COMSOL up
  2. Preparing a COMSOL model for simulations on the cluster
  • Parameters, parametric sweeps, probes, probe tables​
  1. Running parallel COMSOL jobs on Triton using job arrays – basic method​
  • Leveraging SLURM_ARRAY_TASK_ID​ and COMSOL batch license
  1. Advanced methods
    • Multi-level loops and custom parameter lists

When: Wednesday 2025-09-17, 9:00-14:00 (incl. lunch break 11:00-12:00) in zoom or on-site in Otaniemi

The tutorial will be held in a hybrid mode, both on-line (zoom) and with possible on-site participation in Otaniemi. Extra support will be offered in the SciComp zoom garage on the following Thursday and Friday at 13:00.

To join this training, please .

If you do not have one, please . 1 ECTS credit is available for doctoral or master students enrolled in .

Remote and in-person locations will be sent to registered participants on the previous day.
