Saturable materials can be used in the Eddy current solver:

‐ Enter BH curve the same way as in Transient solver

‐ Maxwell will iterate the determine the equivalent operating point


Winding setup is the same as transient except additional phase input

• R16 and before: only current sources were possible

• R17: voltage source, circuit coupling available


涡流场支持GPU加速

GPU only kicks in where there are more than 2 Million unknowns

Using GPU consumes 1 HPC pack

The option needs to be selected in the HPC and Analysis Option panel


涡流场支持GPU加速

Example: High permeable/conductive core

2.07 Million elements

3.51 Million unknowns

Solve time (8 cores): 40min 52

Solver time (8cores + 1 GPU): 20min26

In general, expected speed up is between 1.5 to 2 using one GPU

• Problem: takes very long time to reach steady‐state due to very slow decay of DC flux component, especially with large time constant

• Solution: add an additional voltage component during the 1st half cycle for DC flux linkage to quickly decay to zero.

• Applicable for all types of transient applications.

• Can be combined with Time Decomposition Method

瞬态分析快速达到稳定状态

Before Using Fast Reach Steady State

Set frequency



For electrical machine, further speed up can be achieved using a fixed rotor simulation as initialization step

瞬态分析快速达到稳定状态

Locked Rotor simulation using Fast Reach Steady State

Steady state is reached much faster

Long transient when not use Fast Reach Steady state


• Multiple rotational motions allowed

• One band should not overlap with another band
