Detailed Description

Zero-dimensional fixed pressure constraint. Should be used in conjunction with the zeroDimensionalFixedPressureModel.

This constraint and model facilitates specification of a constant or time-varying pressure. It adds mass source terms proportional to the error that remains when the pressure equation is evaluated at the desired pressure. Iteration may be necessary to converge the constraint in the case of non-linear equations of state.

Properties are added or removed with their current value. The model therefore represents a uniform expansion or contraction in infinite space.

Usage

Example usage:

{
    type            zeroDimensionalFixedPressure;

    // Name of the pressure field, default = p
    //p               p;

    // Name of the density field, default = rho
    //rho             rho;

    // Pressure value
    pressure        1e5;
}
