Re: running MeshMaker file that includes atmosphere and soil
Hi Shirin, I do not understand your question. The meshmaker assigns the first rock type to all the elements in your mesh. Most likely you will need to modify them.…

Re: running MeshMaker file that includes atmosphere and soil
Hi Shirin, First of all you do not need to have positive Z direction to assign atm BC. The coordinates are for plotting, but are not used in the code. Second,…

Re: INSTALL OF TOUGH2
Hi Shirin, I do not see any error here. It seems the input file asks to run 1 time step, which is set to 1.e-9. And that is exactly what the code did. Please make sure you post your message with…

Re: Error in EXT.exe
@Ye Lei Yes, change the maximum number of gird block to a bigger (than yours) number. You may also need to make other array size bigger as well.

Re: Error in EXT.exe
It seems your problem size is larger than the maximum array size defined in the code. Why do not check the total number of grid blocks, the connections and modify the maximum arrays accordingly

Re: Polygonal mesh model runs much slower than regular mesh
Hello Jing, You need to provide more context: Are you running the same problem for both meshes? How does your polygonal mesh look like (e..g, is it still Voronoi grid)? Why is it slow (e.g.…
