Problem while running ground water flow model using benchmark file

Hi everyone,
I am trying to build the ground water flow model in OGS6 using benchmark file Richardflow_2d_small. While running the simulation I am constantly getting the error message saying “You are trying to build a local assembler for an unknown mesh element type (class MeshLib::TemplateElement). Maybe you have disabled this mesh element type in your build configuration or this process requires higher order elements. at LocalDataInitializer.h, line 213”.

Since I am a new user. I couldn’t upload files. (66.3 KB)


your mesh contains line elements which should not exist. You probably forgot to add Physical Surface(1) = {1}; in your gmsh file. In addition, the correct way to comment a line in the geometry file is to use <!--...-->.
