Coefficient Values (CVL) Files

These files may be produced when you carry out a data manipulation task. They may also be produced from a model containing equations if you do not carry out a simulation (for example, you may wish to examine the values of various coefficients to see why the simulation crashed).

A CVL file is produced only if you include a statement of the form

cvl file = … ;

in your Command file.

CVL files are very similar to SLC files in the sense that they contain the values of all Coefficients from the relevant TAB file. Indeed, they contain the values of the Coefficients as they are at the end of the TAB file. [If a Coefficient is used to hold different values during a run, the values stored on the CVL file and the values shown when you load this file into AnalyseGE are those when GEMSIM or the TABLO-generated program reaches the end of the TABLO Input file. You cannot see any intermediate values.]

If you use AnalyseGE to load a CVL file produced from a TAB file containing variables and equations, there are no values available for the variables (since you did not carry out a simulation). However, AnalyseGE lets you select and evaluate expressions involving Coefficients from Equations in the TABmate form.

CVL files have suffix .CVL .

CVL files produced by Release 9 or later of GEMPACK are Header Array files.

However CVL files produced by Release 8 or earlier of GEMPACK are not exactly Header Array files. However most of the data in these old CVL files are in Header Arrays -- and can be viewed in ViewHAR. If you do so, you will need to select option Ignore bad headers under ViewHAR’s File | Options… menu item.

CVL files can contain the values of system-inititated coefficients (the ones created by TABLO when you do condensation - see the GEMPACK manual).
