When we attach a pipe or structural support to a bend, what's the SIF supposed to be?
— Piping codes don't address these and many other geometries that we build in practice every day.

For these and other problems, finite element analysis (FEA) is the answer, but the ability to
build FEA models, generate good results and relate the results to meaningful piping code stresses
and allowables requires expertise or time that most stress engineers don't have.

FEATools is a unique collection of FEA software applications specifically developed to solve
piping & vessel problems that beam element and current code limitations prevent you
from solving accurately.

Why is this important?
Take the large diameter pipe issue - in many cases, stresses and loads are calculated and reported to be much higher in beam analysis programs when compared to reality.
With larger pipe, the solutions to problems that don't exist cost a lot more than solutions to smaller-bore piping problems (where beam theory provides more accurate answers).
The result is that many engineers re-route pipe or otherwise spend a lot of money solving problems that don't really exist.

Wouldn't it be nice to click a button & get a better answer?
That's exactly what one of the utilities in the FEATools library does. You point to a CAESAR file,
and FEATools reads the file, identifies the Tees, performs FE analysis, calculates flexibilities and
SIFs, then create a new CAESAR model with these new properties in the model.

The results can be alarming, and it's so easy to do. To accomplish the same task in the past would
require running FEA software separately, generate the new SIFs and flexibilities, then make
elaborate modifications to the pipe stress model to reflect these changes; very time consuming.
