Perform a DC operating point solution with capacitances open circuited and inductances short circuited. Usually a DC solution is performed as part of another analysis in order to find the operating point of the circuit. Use .op if you wish only this operating point to be found. After a .OP simulation, when you click on a node or current in the schematic, the .OP solution will appear as a level in the waveform viewer. In this mode of crossprobing, there is no information plotted on the horizontal axis.
There is no guarantee that the operating point of a general nonlinear circuit can be found with successive linear approximations as is done in Newton-Raphson iteration. Should direct Newton iteration fail, LTspice tries a number of other methods to find an operating point. Below is a table of the methods used and the options settings required to disable a particular method.
| Method | Directive to disable |
| Direct Newton Iteration | .options NoOpIter |
| Adaptive Gmin Stepping | .options GminSteps=0 |
| Adaptive Source Stepping | .options SrcSteps=0 |
| Pseudo Transient | .options pTranTau=0 |
