In mathematics and particularly in dynamic systems, an initial condition, in some contexts called a seed value,: pp. 160 is a value of an evolving variable at some point in time designated as the initial time. For a system of order k and dimension n, generally nk initial conditions are needed in order to trace the system's variables forward through time. In both differential equations in continuous time and difference equations in discrete time, initial conditions affect the value of the dynamic

Definition of initial condition. : any of a set of starting-point values belonging to or imposed upon the variables in an equation that has one or more arbitrary constants.

Initial conditions are commonly estimated according to capillary–gravity equilibrium conditions in a multiphase system of the reservoir under study. First-type, or Dirichlet, boundary conditions denote constant or time-dependent phase pressure and saturation conditions.

In mathematics and particularly in dynamic systems, an initial condition, in some contexts called a seed value, is a value of an evolving variable at some point in time designated as the initial time (typically denoted t = 0). For a system of order k (the number of time lags in discrete time, or the order

The only possible inequivalent 1 2 initial conditions are { {1,1}}, corresponding a graph consisting of a single self-loop, and { {1,2}}, consisting of a single edge. The possible inequivalent connected 2 2 initial conditions are: Copy to clipboard. These correspond to the graphs: Copy to clipboard. The possible inequivalent 1 3 initial conditions are:

Defining initial conditions in Abaqus/Standard and Abaqus/Explicit. Required parameters. TYPE. Set TYPE = ACOUSTIC STATIC PRESSURE to define initial static pressure values at acoustic nodes for use in evaluating the cavitation status of the acoustic element nodes in Abaqus/Explicit .

x(0+), x(0+),. . . the post-initial condition. Important: Hereafter when we just say initial conditions we will mean the pre-initial conditions. In cases where x(t) is smooth the pre and post-initial conditions are the same and their is no need to distinguish between them. 2. Simple Examples Example 1. Consider the initial value problem .

This type of initial condition is typically used to define the initial velocity of a component of a rotating machine, such as a jet engine. The initial velocities are specified by giving the angular velocity, ω ; the axis of rotation, defined from a point a at X a to a point b at X b ; and a translational velocity, v g .
