2025 Release Notes

Release notes describe features as they exist at the time of publication. Some names, paths, and other details may have changed since publication.

December 18, 2025

  • You can now use compressed input files to run jobs from spaces. Create an input directory in the space as usual, and then upload your case as a zip or tar file. This file must be named inputs.zip or inputs.tar.gz, and it must contain the case files in the root directory of the archive. After you create the job, CONVERGE Horizon will automatically extract the files on the job cluster before starting the simulation.

  • Added node metrics for file systems.

  • Added disk IOPs as a node metric for both jobs and file systems.

  • Added an option to the Transactions page to filter transactions by team.

December 8, 2025

  • The BM-AMD-TURIN-256 and VM-AMD-TURIN-FLEX node types are now available in the Japan Central (Osaka) data center.

December 3, 2025

Improvements and major changes:

  • Renamed all node types for jobs to include processor generation (TURIN, ICELAKE, etc.). Additionally, the names of VM node types now include the word FLEX instead of the number of cores on the underlying hardware.

  • Renamed all node types for workstations to include processor manufacturer (INTEL).

  • Improved file loading in spaces.

  • Files in spaces can now be sorted by name, size, and the date last modified.

  • Added the job:show command.

  • Added the --batch_id option to the job:list command.

Required follow-ups:

  • All CLI users must upgrade to version 2.7.1 or later.

November 5, 2025

  • Added an option to hibernate a file system. This deletes the VM node while retaining your data, so you do not have to pay the hardware cost of the node during hibernation. You still have to pay storage costs during hibernation.

  • Workstations are now available in the US West (Phoenix) data center.

  • All team members who have set up SSH keys can now SSH to jobs and workstations owned by other team members. This change will take effect for jobs and workstations created after this release. Previously, only team managers could SSH to jobs and workstations owned by other team members.

  • You can now configure lifecycle policies to automatically delete files from a file system after a specified number of days.

October 7, 2025

Improvements:

Required follow-ups:

  • All CLI users must upgrade to version 2.5.7. After upgrading, run the config:create command to update your CLI configuration.

September 2, 2025

  • Spaces are no longer associated with projects.

August 29, 2025

  • Added load balancer for faster job startup in the Japan Central (Osaka) data center.

August 28, 2025

Improvements and major changes:

  • Added file systems as a new cloud storage option. You can now run jobs on file systems or spaces. Pricing information is available at convergecfd.com.

  • Added the US West (Phoenix) data center, which offers the following node types: BM-AMD-192, BM-AMD-256, BM-INTEL-36, VM-AMD-192, and VM-AMD-256.

  • Improved job startup times for jobs running on virtual machines (VMs).

  • Improved cluster provisioning so that fewer jobs will fail with the reason “Cluster provisioning failed”.

  • You can now receive email notifications triggered by specific events (for example, you can receive emails only when jobs fail).

  • Removed the option to terminate a job.

  • Added an option to discard output data when stopping a job. This is functionally equivalent to the previous option to terminate a job.

  • Deprecated the job:terminate command and added new options to the job:stop command.

  • The option to terminate a workstation has been renamed as Delete.

  • Simplified job statuses and workstation statuses. Jobs that were previously marked as Completed are now marked as Stopped with the exit reason “CONVERGE completed”.

  • On the Job Details, Workstation Details, and File System Details pages, you can now view a system log with detailed status information from the CONVERGE Horizon back end.

  • When you run a job in Interactive mode, files are no longer copied to and from the job cluster automatically. You must transfer files manually with the CLI.

  • For jobs run from spaces, the path to scratch storage on the job cluster has changed from /mnt/scratch/case to /mnt/fs/files.

  • When you add an SSH key to your account, the key now works for all active resources for which you have SSH permissions. Previously, the key would only work for resources created after the key was added.

Required follow-ups:

  • All CLI users must upgrade to version 2.4.2 or later.

  • If you previously configured email notifications, your configuration is no longer valid. Go to My Account > Email Notifications to reconfigure your preferences.

  • If you have any scripts that use the path /mnt/scratch/case, update the path to /mnt/fs/files. We have added a temporary symlink from the old path to the new path, so your scripts will not break immediately. We still recommend updating your scripts as soon as possible, because the symlink will eventually be removed.

June 13, 2025

  • Adjusted hardware costs for the VM-AMD-192 and VM-AMD-256 node types. These adjustments will result in lower prices for VM nodes across all subscription tiers for jobs using the Horizon-Hosted or Self-Hosted CONVERGE license type. The new costs are incorporated in the cost estimate when you create a new job, and they are also reflected in the Cost Estimator at convergecfd.com.

June 10, 2025

  • Added support for optional coupling with GT-SUITE. This option is available only when creating jobs in the web interface. It will be added to the CLI in a later release.

  • Redesigned the Create Job page. Some job options that were previously under Advanced Options have moved to other sections.

  • Redesigned the Create Workstation page.

June 2, 2025

  • Added the BM-AMD-256 and VM-AMD-256 node types, which are based on the latest generation of AMD EPYC processors (Turin).

  • Removed the BM-AMD-128 node type.

  • Renamed the existing VM-AMD-FLEX node type to VM-AMD-192. These nodes are still provisioned as virtual machines with the number of cores that you request. The name change reflects the total number of cores on the underlying processor.

  • Updated pricing for existing hardware and software options. Complete pricing information is available at convergecfd.com. The new pricing will also be incorporated in the cost estimate when you create a new job.

  • Added notifications for stuck jobs. If the horizon.log file for a running job has not been updated for over an hour, the job owner will be notified.

May 19, 2025

May 2, 2025

  • Added the India South (Hyderabad) data center for BM-AMD-192 and VM-AMD-FLEX nodes.

April 11, 2025

  • Folder deletions in spaces are now processed in the background. When you delete a folder, you will see a message indicating that the folder will be deleted. If the folder contains a large number of files, this process may take some time.

  • Fixed bugs in which:

    • Spaces could get stuck at Emptying or Deleting status.

    • Jobs could get stuck at Stopping status.

    • Large folders were not always deleted entirely when you tried to delete them.

March 19, 2025

  • Because of changes in the resources available from our cloud provider, workstations will be unavailable in the Toronto data center until further notice.

March 15, 2025

  • Updated the CLI. All CLI users must upgrade to version 2.0.2 or later. After upgrading, run the following commands (you can copy your <API key> from My Account > My API Key):

    # Linux and MacOS
rm -f ~/.config/horizon/config.json
horizon config:create <API key>

# Windows command prompt (cmd)
del %USERPROFILE%\.config\horizon\config.json
horizon config:create <API key>

  • The config:team command has been renamed to team:switch.

  • When uploading files to a space in the web interface, you can now click Upload Folder to upload an entire folder from your local machine.

January 16, 2025

  • The workstations feature has exited beta and is now in official release.
