May you kindly assist me, I am using rheoTool. Trying to run the rheoFoam solver using the one of the tutorials provided GiesekusLog. In the solver provided they are simulating the fluid flow in a channel. I want to simulate this using a wedge, I tried using one of the blockMeshDict files from the rheoFoam GNF - Newtonian tutorial .It gives me the below errors all and I did was to change the geomerty from a channel to a wedge. I further tried to create my own circular pipe blockMesh but it still gives me the below error
