ana1Tests.energyLineTest.getAlphaProfileIntersection

getAlphaProfileIntersection(energyLineTestCfg, avaProfileMass, mu, csz)

Extend the profile path and compute the intersection between the theoretical energy line and the path profile The profile is extended by a line. The line slope is computed from the slope of the regression on the last points of the profile

Parameters

• energyLineTestCfg (configParser) – energy test config

• avaProfileMass (dict) – particle mass average properties

• mu (float) – friction coefficient

• csz (float) – dem cell size

Returns

• slopeExt (float) – slope of the extrapolation line

• sIntersection (float) – s coord of the intersection between the line of slope mu and the mass average path profile

• zIntersection (float) – z coord of the intersection between the line of slope mu and the mass average path profile

• coefExt (float) – coefficient saying how long the path was extended to find the intersection
