Hi Amita:
The dataset that is struggling was created in Power InRoads (SELECTSeries 4), so there shouldn't be a mismatch in the parameters, which is what is making it really strange. I'm happy to upload the alg., dtm, and xin that we have been using. to see if you can spot why it doesn't work.
What would be the best way of sending this to you?
Thanks,
Paul Tonkin
