Perhaps you should try some spelling variations:
"advanced computacionais _ computer program" » "advanced computational _ computer program" (Expand search), "advanced computations _ computer program" (Expand search), "advance computational _ computer program" (Expand search)
"using computational fluid example of" » "and computational fluid example of" (Expand search), "using computational fluid sample of" (Expand search), "using computational fluid samples of" (Expand search), "using computational field example of" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computacionais _ computer program\") OR (\"using computational fluid example of\"))~".
• Removing quotes may allow a broader search: (( advanced computacionais _ computer program ) OR ( using computational fluid example of ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computacionais _ computer program") OR ("using computational fluid example of"))*.
