Hi all

I've successfully run a simple 3D flow simulation and wish to extract data on the various components of velocity between 2 x-locations at different y and z planes.

This can be done successfully manually inside paraFoam by using 'plot over line' and for the plane y = 0 and z = 0; however when I try and alter either the y or z values in the sampleDict file I come up with the following segmentation error:

Create mesh for time = 0

Segmentation fault


Is this an error with the program or am I incorrectly setting up the sampleDict file?
Cheers.
Dom.
