  • Irregular elevations

    Hi, I created the elevation profile for my study area, and it looks very undulated in FEFLOW 8.1. I followed the introductory tutorial for 8.1 and generated the elevation for three layers using inverse distance interpolation. After that, I tried both the Triangle and Grid Builder meshing options, but the result looks irregular. When I performed the same process for two layers using the same elevation data in FEFLOW 7.4, the elevation profile came out smooth. Is this a version issue, or did I miss something?
