SHD Sim EM
Magnetostatics
Permanent magnets, DC coils, forces
Elmer
In development.
This module is phase 3 — after structural and thermal. The solver behind it is chosen and its capability is known. SHD Sim is available today.
What it is
The magnetic field from permanent magnets and steady currents, and the forces it produces. Iron saturates, so the nonlinear B-H curve matters as soon as the design works near its limit, and most good designs do, because iron is the expensive part.
What this analysis needs from you
- A B-H curve for the ferromagnetic materials, not just a permeability
- Coil currents or magnet remanence
- An air region around the model, since the field lives there too
Typical uses
- Permanent magnet circuit design
- Solenoid and actuator force curves
- Magnetic separator and holding magnet sizing
- Shielding against a static field
Industries
Sectors where this analysis is routinely asked for.
- Electric machines
- Magnetic separators
- Sensors & actuators
- Scientific instruments
What comes out
- Flux density distribution
- Saturation regions in iron
- Force on parts and armatures
- Air-gap field quality
Backend
Elmer
Chosen for this analysis type, with its capability verified against the module plan — not decided later.
Status
Phase 3 — after structural and thermal. Telling us you need this analysis moves it up the order — modules are sequenced by who is waiting for them.
