Perhaps you should try some spelling variations:
"using computational and modelling problems" » "and computational and modelling problems" (Expand search), "using computational and modelling process" (Expand search), "using computational and solving problems" (Expand search), "using computational and covering problems" (Expand search), "using computational fluid modelling problems" (Expand search), "using imputational and modelling problems" (Expand search), "using compilational and modelling problems" (Expand search), "using coaptational and modelling problems" (Expand search), "using computational and modeling problems" (Expand search)
"using computation and coding program" » "using imputation and coding program" (Expand search), "using compilation and coding program" (Expand search), "using coaptation and coding program" (Expand search), "using computation of coding program" (Expand search), "using computation and cloning program" (Expand search), "using computation and loading program" (Expand search), "using computation and cooling programs" (Expand search), "using computation and coping program" (Expand search), "using computation and cooling program" (Expand search), "using computation and cooking program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("using computational and modelling problems") OR ("using computation and coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational and modelling problems\") OR (\"using computation and coding program\"))".
• Removing quotes may allow a broader search: (( using computational and modelling problems ) OR ( using computation and coding program )).
• Adding a wildcard symbol may retrieve word variants: (("using computational and modelling problems") OR ("using computation and coding program"))*.
