3.7.5 NDAESolve
NDAESolve[dae, {tvar, t }]
computes the DC solution of a nonlinear DAEObject dae at
the time point tvar ⩵ t
NDAESolve[dae, {tvar, t }, params]
carries out a parametric DC analysis
NDAESolve[dae, {tvar, tstart, tend}]
computes the transient or the DC-transfer solution of a
nonlinear DAEObject dae within a specified integration
interval tstart tend as function of the independent
variable tvar
NDAESolve[dae, {tvar, tstart, tend}, params]
carries out a parametric transient or a parametric
DC-transfer analysis
Command structure of NDAESolve.
The function NDAESolve allows for carrying out several numerical analyses, such as an operatingpoint
(DC) analysis, a DC-transfer (DT) analysis, or a large-signal (transient) analysis. NDAESolve
returns the result according to the Analog Insydes numerical data format described in Section 3.7.1.
It consists of lists of rules, where the variables are assigned InterpolatingFunction objects in case
of a transient analysis or numerical values in case of a DC analysis. Both analysis modes can also
be carried out as parametric analyses. For this, specify a parameter sweep params according to the
Analog Insydes parameter sweep format described in Section 3.7.2.
The result of the numerical transient analysis can be displayed with Analog Insydes graphics
functions such as TransientPlot (Section 3.9.6).
Note that NDAESolve still supports the command structure from Release 1 where the first argument
is given as {eqns, vars} instead of a DAEObject:
NDAESolve[{eqns, vars}, {tvar, t }]
carries out a DC analysis
NDAESolve[{eqns, vars}, {tvar, t }, params]
carries out a parametric DC analysis
NDAESolve[{eqns, vars}, {tvar, tstart, tend}]
carries out a transient or a DC-transfer analysis
NDAESolve[{eqns, vars}, {tvar, tstart, tend}, params]
carries out a parametric transient or a parametric
DC-transfer analysis
