MODEL GENERATION FOR AN ULTERIOR
ANALYSIS WITH FEBIO.
PREVIEW CONSISTS IN A GUI WITH A 3D
ENVIRONMENT THAT ALLOWS 3D ITEMS
TO BE CREATED FROM BASIC SHAPES.
IN THIS ENVIRONMENT ALL GEOMETRIC
ELEMENTS ARE DEFINED AND MODELLED,
AS WELL AS GIVEN THEIR MATHEMATICAL
PROPERTIES SUCH AS BOUNDARY
CONDITIONS OR RIGID CONSTRAINTS TO
BE PROCESSED WITH FEBIO.

WHY IS IT A GOOD SOLUTION?
FEBIO
IS A SOLUTION CREATED SPECIFICALLY FOR BIOMEDICAL DATA,
AND IS A POWERFUL TOOL FOR SOLVING GENERAL

WHAT ARE ITS HIGHLIGHTS?
PURPOSE FEM.
FEBIO IS A SOFTWARE THAT IS CAPABLE OF MAKING TRUSTWORTHY
REPRESENTATIONS (MODELS) OF BIOMEDICAL DATA AND… IT’S FREEWARE!
AS MANY FREEWARE SOLUTIONS, IT’S BEING DEVELOPED AND IMPROVED
EVERYDAY.
 IS IT
“COMPLETE”?
FEBIO SUITE INCLUDES THREE PROGRAMS: PREVIEW, FEBIO AND POSTVIEW.
THIS SOFTWARE IS PREPARED TO WORK AS A WHOLE, AS ONE CAN MODEL,
CALCULATE AND INFER RESULTS WITH ONE SINGLE PROGRAM. IT NEEDS AN
UPDATE RELATED TO FLUIDS AND MORE TOOLS TO EXTRACT INFORMATION IN
POSTVIEW.
