The program (Pipe Plus) recommends setting the -ExpGapInd option when dealing with non-linear supports. I have a pipe supported by several vertical one-way supports (non-linear), and anchors in both ends. When the pipe is hot, some of these one-ways (the ones near the anchors) are lifted up from the support structure, this means that the pipe has a positive vertical displacement, leaving the supports "floating". Running the analysis first without the -ExpGapInd option, and then with it, gives very different results (looking at the support summary). I am not sure which results should I trust. Any help appreciated, sorry for my poor English...
