3. DESCRIPTION OF PROGRAM OR FUNCTION

FLOWPLOT2 is a plotting program used with numerical or analytical fluid dynamics codes to create velocity vector plots, contour plots of up to three fluid parameters (e.g. pressure, density, and temperature), two-dimensional profile plots, three-dimensional curve plots, and/or three-dimensional surface plots for either the u or v velocity components. If the fluid dynamics code computes a transient or simulated time related solution, FLOWPLOT2 can also be used to generate these plots for any specified time interval. Multiple cases generating different plots for different time intervals may be run in one execution of the program. In addition, plots can be created for selected two- dimensional planes of three-dimensional steady-state problems. The user has the option of producing plots on CalComp or Versatec plotters or microfiche and of creating a compressed dataset before plotting.

4. METHOD OF SOLUTION

FLOWPLOT2 reads a dataset written by the fluid  dynamics code. This dataset must be written in a specified format and must contain parametric data at the nodal points of a uniform or non-uniform rectangular grid formed by the intersection of the grid  lines of the model.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Maxima of

   2500 nodes
     40 y-values for 2-D profile plots and 3-D curve plots
     20 contour values
      3 fluid parameters

7. UNUSUAL FEATURES OF THE PROGRAM

Although FLOWPLOT2 assumes that a  rectangular grid is used to specify the fluid dynamics, approximate  results on non-rectangular subgrids can be generated by enclosing the entire subgrid for which parametric data is desired within a rectangular grid.

8. RELATED AND AUXILIARY PROGRAMS

FLOWPLOT2 is a revision and extension of FLOWPLOT. The variable dimensioning technique used in FLOWPLOT has been updated in FLOWPLOT2: however, the FLOWPLOT ability to generate plots at interpolated time levels is not included in FLOWPLOT2. Contour plots are generated using a version of the CONPLT plotting package.
