Time Domain Solver Problem HandlingThis page contains a list of the most important warning and error messages in the context of the transient solver together with a detailed explanation of the meaning and proposal for handling and resolution. Maximum number of pulse widths simulated, solver stopped. / Maximum simulation time reached, solver stopped. Please note that the steady state energy criterion has not been satisfied.The transient solver operates with a time pulse as excitation, and the simulation stops when one of the following conditions are met:
The warning appears when the latter condition was satisfied first before the accuracy level has been reached. This means the energy level remaining in the structure is still bigger than the specified steady state value. Usually this is the case for resonating (energy stays inside the structure for a long time) or large structures (it takes a long time for a pulse to penetrate through the structure). The extra energy would appear as a truncation error, which causes some ripples in the S-parameter curves. Recommended solutions are the following:
Farfield probe "xxx" is not considered in time domain calculation because it is positioned below a closed boundary referring to the origin setting. In general a point or probe location on a farfield sphere is determined by a direction and a radius, i.e. a three dimensional vector r(farfield). In Cartesian coordinates this is given by the definition of two spatial points, the probe position r(probe) and the origin r(origin). The vector for the farfield calculation is then given as r(farfield) = r(origin) - r(probe). The above warning is shown when this vector points below a certain closed boundary.
