To　effectively　prevent　and　accessorily　treat　the　diabetic　foot,　the　applications　of　modern　technology　to　prevention　and　accessorily　treatment　of　diabetic　foot　possess　very　important　realistic　significance　and　applied　value.　Geometry　model　of　foot　is　created　with　image　manipulation　software　and　CAD　software.　Finite　element　model　is　created　with　MSC/Patran　software,　which　is　the　pre-processing　software　of　finite　element　analysis　software.　And　the　stress　distribution　on　the　bottom　of　foot　is　analyzed　with　MSC/Nastran　software,　which　is　finite　element　analysis　software.　With　MSC/Patran　software　as　the　developing　platform,　the　program　is　compiled　with　advanced　programming　language　MSC/PCL　to　automate　the　process　of　model　manipulation.　The　program　can　automatically　manage　the　geometry　model　to　create　the　finite　element　model,　so　the　manual　intervention　is　reduced　and　the　efficiency　is　improved.　The　foundation　for　the　optimization　design　of　the　facility　to　prevent　and　accessorily　treat　the　diabetic　foot　is　established　with　the　combination　of　image　manipulation　and　numerical　simulation.
