How Case Generation Works

From a template file plus an Excel cases table to N output files in three steps.

1

Open the Case Generator pane

Pick Case Generator from the Tools group on the Petroleum Office ribbon. The pane opens with empty Step 1 (template path), Step 2 (Excel ranges), and Step 3 (preview & validate) sections.

2

Point at your template

Browse to a text file with <%TOKEN%> placeholders — an ECLIPSE deck, a CMG input, any plain-text simulation file. The path resolves and you're ready to map ranges.

Map Excel ranges and generate

Point Tokens, Cases, and Values at the matching Excel ranges — tokens as a header row, cases as a column, values as the inner block. The preview validates everything; click Generate Files to write one output file per case row.

One small Excel table, N output files

Each row in your case table becomes one generated file alongside the template — tokens replaced with that row's values. The whole loop lives in Excel: edit the cases, hit Generate, ship the deck.
