Specifies the maximum slope of a straight pipe element for which thermal bowing effects will be considered.
Thermal bowing is usually associated with fluid carrying horizontal pipes in which the fluid does not fill the cross section. In these cases, there is a temperature differential across the cross section. You can use Horizontal Thermal Bowing Tolerance to define the interpretation of "horizontal." By default, the software uses a value of 0.0001 as the horizontal threshold value. If a pipe element’s pitch is less than this tolerance, the element is considered to be horizontal, and thermal bowing loads can be applied to it. An element’s pitch is computed using the following formula:
PITCH = | DY | / ( DX2 + DY2 + DZ2 )1/2
