Disc Spring Solver: calculator for Belleville washers and disc springs problems

Report template

In addition to the possibility of modifying the report using the included html editor, Disc Spring Solver allows the user to create and use a report template in order to make more easy for the user to place the wanted data everywhere in the report and to save this report configuration.

To load a template you just need to load an html file selecting "Load a template" from the "Report" menu.

To let Disc Spring Solver know where to put the wanted data into the template, you need to insert, during the html report template (you can use the included html editor or your favorite editor), some special strings that will be replaced with the wanted value (or picture) once that the template has been loaded in Disc Spring Solver.
You need also to insert some special comments inside the report html code in order to let Disc Spring Solver know which components of the report are desired.

In the included example template, that you can also find here (of course you can not see picturs because link are at the moment replaced by the strings that you can find in the list "Strings for pictures"), all the strings and all the comments that you need are shown, you can see below the list of all the elements (strings and comments) and the values used to replace them (if the value to replace has not been calculated, the string will be replaced with "N/A"):
