SERGIO BLANCO TREJOGUILLERMO JIMÉNEZ PÉREZDAVID LÓPEZ CARRILLO
NUMERICAL TECHNIQUE FOR FINDING APPROXIMATE SOLUTIONS TO BOUNDARY VALUE PROBLEMS FOR DIFFERENTIAL EQUATIONS
IT STARTS FROM AN INITIAL STATE AND FROM THERE IT CALCULATES OTHER MOMENTS APPLYING A SET OF FORCES AND BOUNDARY CONDITIONS
FINITE ELEMENT ANALYSIS
STATE OF THE ART SOFTWARE FOR ANALYSIS USING FEM STEPS FOR MODELING:
◦ CREATION OF GEOMETRICAL FIGURES◦ MESHING -> VOXEL, TRIANGULATION,
TETRAHEDRAL MESHES◦ ADDITION OF PHYSICS
NOT MANYWORKING SUITES FORBIOLOGICAL MODELS

PREVIEW
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.
FEBIO CONSISTS OF THREE PARTS:
PREVIEW
FEBIO
FEBIO IS CONTROLLED THROUGH A CLI
ONLY PERFORMS CALCULATIONS
REQUIRES HIGH PROCESSING
FEBIO CONSISTS OF THREE PARTS:
POSTVIEW IT USES THE SAME
3D VIEWER AS PREVIEW
SIMPLE CALCULUS PLOTTING OF
PHYSIC DATA PLOTTING OF
STATISTIC DATA
FEBIO CONSISTS OF THREE PARTS:
POSTVIEW
BIOMEDICAL APLICATIONS
AND MUCH MORE
(…)
AND SOME INTERACTIVE EXPERIENCE
WHY IS IT A GOOD SOLUTION?FEBIO IS A SOLUTION CREATED SPECIFICALLY FOR
BIOMEDICAL DATA, AND IS A POWERFUL TOOL FOR SOLVING GENERAL PURPOSE FEM.
WHAT ARE ITS HIGHLIGHTS?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.
