Customer's Feedback

It was really a fun experience using S-FOUNDATION. It is an easy-to-use software especially with an attractive interface (GUI). I have been teaching soil mechanics, geotechnical engineering & foundation engineering courses for the past 17 years in Malaysia with experience in PLAXIS.
