CEM – GPU Electromagnetic Simulations with Palace

CEM turns Palace, the open-source 3D finite element solver for computational electromagnetics, into a ready-to-use web application on a GPU virtual machine in your own Azure subscription. Your engineers set up, check, run and evaluate electromagnetic simulations in the browser, without building a cluster, compiling solvers or moving data out of your tenant.

Who it is for

RF and microwave engineers, antenna designers, signal-integrity teams and superconducting quantum-hardware groups, in industry and research, who need full-wave 3D simulations: resonant modes and quality factors, S-parameters, time-domain pulses, capacitance and inductance matrices. IT teams get one self-contained deployment that they control.

Simulate

Optional AI assistance

Connect your own model (Anthropic, Google Gemini, Azure OpenAI or another OpenAI-compatible API) for an AI review of your configuration, advice when a case fails its checks, suggested job names, and an analysis with a corrected configuration when a run fails. Without a key these features are off, and simulations never depend on them.

Supported VM sizes

Pricing and requirements

An hourly software fee per VM hour, shown before you deploy, plus the Azure resources you use (VM, disks, public IP address, optional storage). Stop (deallocate) the VM when it is idle: software and compute charges pause, disks remain billed. You need quota for the chosen GPU size in your region. One simulation runs at a time and uses the GPUs you select.
