Problem running simulation cases
LeeStr1 opened this issue · comments
All the simulation cases have problem creating mesh due to insufficient RAM on my system. Even though, I have allocated 50% of my computer's total RAM (16 GB). Everytime I run blockMesh or snappyHexMesh, the process gets killed in midway.
I was able to run "nucleateBoiling_BuresSato" blockMesh by reducing the mesh size to 2.0e-4 (which is originally 2.0e-6 in the tutorial).
But, At the time of running the solver, I got the following error, "Cannot find file "points" in directory "heater/polyMesh" in times "0" down to constant". I guess, because of big mesh size, the heater cellZone can not be splitted.
So, what can I do to solve this issue?
Q: All the simulation cases have problem creating mesh due to insufficient RAM on my system. Even though, I have allocated 50% of my computer's total RAM (16 GB). Everytime I run blockMesh or snappyHexMesh, the process gets killed in midway.
A: I don't know what to do about that, try buying a better computer.
Q: I was able to run "nucleateBoiling_BuresSato" blockMesh by reducing the mesh size to 2.0e-4 (which is originally 2.0e-6 in the tutorial).
A: nucleateBoiling_BuresSato at full resolution works perfectly fine on my workstation using far less than 16GB of RAM.
Q: But, At the time of running the solver, I got the following error, "Cannot find file "points" in directory "heater/polyMesh" in times "0" down to constant". I guess, because of big mesh size, the heater cellZone can not be splitted.
A: It means that the mesh was not created for whatever reason.
Q: So, what can I do to solve this issue?
A: If your issue is about memory in your computer, there is little I can do to help you.
