Maximum Delta E
For designs with voltage sources,
current sources, or incident waves.
Not applicable to designs with ports.
The delta E is the difference in the relative energy error from one adaptive solution to the next. It is a measure of the stability of the computed field values from pass to pass. As the solution converges, delta E approaches zero.
The Maximum Delta E Per Pass value is a stopping criterion for the adaptive solution. If the delta E falls below this value, the adaptive analysis stops. Otherwise, it continues until the convergence criteria are reached.
The data represents the delta E for all tetrahedra.
