A prerequisite for using RetainPro is the ability to design a relatively complex retaining wall by hand. Therefore we assume that if you get results that don't look right, you will question them.
When this occurs, and it probably will occur from time to time, the first step is for you to review your input for errors. In our tech support experience it’s nearly always an input error. If you can’t find the problem, send us your Project File. Be sure to indicate which wall you are referring to and what specific result you are questioning. If you disagree with computed results, send us your disputing hand calcs as well.
A final note: Nearly half the technical support questions we receive involve the stem screen, and nearly always are due to misunderstanding the entries and their sequencing. Before contacting us, please re-read the User’s Manual section on stem design.
