I've recently installed ANSYS version 18.2, and am working on the ANSYS Fluent Tutorial Guide to learn the software starting with the first tutorial.
I'm having issues with mesh generation for any geometries I use, even for simple 3D objects such as cylinders and spheres, and have tried adjusting all mesh parameters but to no success. Following the tutorial guide step-by-step, and testing on different shapes, I am constantly given the same error message each time:
"The mesh generation did not complete due to poor quality elements or incorrect input. Please try meshing with another mesh method or different mesh options. "
I have tested this exact same tutorial and steps on versions 19, 18.0, and now 18.2 and have also had the exact same issue for each of them. I'm quite desperate to find a solution for this as I need to use this software for college, so any help or input on the issue would be greatly appreciated,
